Answer:

The approach of cytokinesis to form cleavage furrows does not work for the plant cells due to specific reasons. These reasons are -

The presence of a rigid outermost layer called cell wall in plant cells that do not allow for forming furrows.

Centrioles present in animal cells helps in maintaining the organisation of mitotic spindle and completion of cytokinesis, however, not found in plant cells. The Golgi vesicles secrets and makes a septum or cell plate in the equatorial plane of the cell wall with the help of microtubules and phragmoplast help in the separation of two daughter cells.

The process of cytokinesis to form cleavage furrows does not function for the plant cells due to the following reasons :

Cleavage furrow is a constriction formed by the actin ring during animal-cell cytokinesis that leads to cytoplasmic division. cytokinesis is the division of the cytoplasm the following mitosis to form two daughter cells.

Thus, the presence of cell walls and the absence of centrioles are the reason.

c. the GTP-bound form of Gas, locking it in the active conformation.

Explanation:

The reason is that the toxin created by the enteric intestinal bacterium Vibro cholerae triggers an exorbitant amount of diarrhea by inducing the excretion of NaCl and enormous amounts of water into the bowel. The mechanism by that epidemic cholera toxin acts is ADP ribosylation of the Gs alpha monetary unit. This implies that G\(\alpha\)s macromolecule protein exploits NAD, therefore protecting it within the active conformation.

Answer:

The correct answer is "identify the order in which rock units formed".

Explanation:

Relative dating methods are experimental approaches that allow to identify the relative order of past events. Instead of determining the absolute age of samples such as rocks or fossils, relative dating methods correlate which samples are older. Therefore, relative dating methods help scientists to identify the order in which rock units formed.

Option 3 is correct, i.e. Rolling friction is smaller than the sliding friction.

●       The opposing forces that are experienced by objects when moving against each other are termed as friction.

●       Static friction, sliding friction and rolling friction are the resistances experienced by stationary, moving and rolling objects respectively.

●       Since static friction keeps an object stationary, it is the maximum.

●       Rolling friction, on the other hand, provides the least resistance as the contact time and contact area between the two surfaces is the least.

Therefore, static friction is the strongest form of frictional force followed by sliding friction which is weaker than static but stronger than rolling friction.

The three requirements for a trait to become more common over time in a population area;

Traits are qualities or characteristics that are shared between living organisms as a result of the transfer of these traits from parents to offspring.

Traits are determined by genes.

Genes are the basic unit of inheritance. Genes are regions of DNA that code for a particular product.

The combination of the genes present in an organism is responsible for the traits that are observed in organisms.

The combination of genes in an organism is known as the genotype whereas the observable traits in an organism is known as the phenotype.

Genes for a particular trait in an organism have alternate forms known as alleles. When an organism has similar copies of the allele for a trait, the organism is said to be homozygous for that trait, but when an organism has different alleles for a trait, the organism is said to be heterozygous for that trait.

The theory of the new corona virus's transfer from bats to people is covered in the explanation that follows.

The severe acute respiratory syndrome coronavirus 2 was produced as a result of cross-species transmission and is the culprit behind COVID19 (SARS-CoV-2). Coronaviruses are a large family of viruses that may infect a variety of hosts.

The host ACE2 protein and TMPRSS2 cleavage of the surface (S) protein are required for SARS-CoV-2 entrance. ACE2, a species-specific barrier, may prevent the bat-to-human coronavirus from spreading across species boundaries. Bats were confirmed as SARS-natural CoV's hosts by a molecular analysis, and they were also linked to the genesis of MERS-CoV.

A novel coronavirus called the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) evolved as the cause of COVID19 as a result of interspecies transmission.

Coroviruses are a large family of viruses that may infect a variety of hosts. For SARS-CoV-2 entrance, the surface (S) protein must interact with the host ACE2 protein and TMPRSS2 must be cleaved.

The species-specific barrier ACE2 may stop the bat-to-human coronavirus from spreading. A molecular analysis established bats as the SARS-natural CoV's hosts and linked them to the establishment of the MERS-CoV. Given the genetic resemblances between the SARS-CoV-2 strain and the bat RaTG13 CoV strain, it is believed that the most recent outbreak was caused by bats.

Compared to the human TMPRSS2 sequence, the pangolin ACE2 amino acid sequence has a greater evolutionary distance from bats and a lower evolutionary distance from humans. When comparing SARS-CoV and SARS-CoV-2 origins, the civet, the main intermediate host of SARS-CoV, has lesser ACE2 evolutionary divergence with humans than pangolin. The pangolin has evolved into an appropriate host for intermediate SARS-CoV-2 leap and entrance from bat to human as a result.

The study of links and evolutionary histories between or among groups of species is known as phylogenetics. These links are inferred using phylogenetic inference methods that focus on heritable traits that can be observed, including DNA sequences, protein amino acid sequences, or morphology.

The four types of lipids, namely fats, phospholipids, waxes, and steroids, play distinct roles in various biological processes. Fats are primarily involved in energy storage, while phospholipids form the structural basis of cell membranes. Waxes provide protection and waterproofing for plants and animals, and steroids serve as signaling molecules and are involved in various physiological functions.

1. Fats: Fats, also known as triglycerides, are a type of lipid that play a crucial role in energy storage. They are composed of glycerol and three fatty acid chains. Fats are stored in adipose tissue and serve as a long-term energy reserve. During times of energy deficiency, fats are broken down through a process called lipolysis to release energy.

2. Phospholipids: Phospholipids are a major component of cell membranes. They consist of a glycerol molecule, two fatty acid chains, and a phosphate group. The unique structure of phospholipids allows them to form a lipid bilayer in cell membranes, with the hydrophobic fatty acid tails facing inward and the hydrophilic phosphate heads facing outward. This arrangement creates a selectively permeable barrier that controls the movement of substances in and out of the cell.

3. Waxes: Waxes are a type of lipid that serve protective functions in both plants and animals. They are composed of long-chain fatty acids and a long-chain alcohol. In plants, waxes form a waterproof coating on the outer surfaces of leaves, stems, and fruits, preventing excessive water loss and providing protection against pathogens. In animals, waxes are found in structures such as the ear canal, providing lubrication and protection against foreign particles.

4. Steroids: Steroids are a class of lipids characterized by a four-ring structure. They have diverse roles in the body, including serving as signaling molecules and regulating various physiological processes. For example, cholesterol, a type of steroid, is a precursor for the synthesis of steroid hormones such as estrogen, testosterone, and cortisol. These hormones play essential roles in reproduction, development, and metabolism.

Overall, the four types of lipids - fats, phospholipids, waxes, and steroids - each have distinct functions and contribute to various biological processes in organisms.

Lower than normal blood pressure will cause which of the following effects on the rate of clearance of substance A is C. A decrease, because a decrease in the rate of urine output will allow more reabsorption by the kidneys

Kidneys are bean-shaped organs located behind the abdomen which function as excretory organs and play a role in blood control. The kidneys control blood pressure through regulation of extracellular fluid volume and renin secretion. Blood pressure can be caused by a lack of fluid which causes blood volume to decrease, causing a decrease in blood pressure.

Decreased kidney function is characterized by a decreased glomerular filtration rate based on measurements of creatinine clearance, caused by low blood pressure thereby reducing the filtration rate of the glomerulus. This causes the amount of substance A to decrease in the urine due to reabsorption by the kidneys.

Explanation:

what's the question though? lol

Photosynthesis and cellular respiration are two close related and complementary processes. Photosynthesis produces organic molecules and releases oxygen, which are used during cellular respiration to produce water, ATP, and CO₂.

Photosynthesis is a process plant cells go through when absorbing sunlight.

During photosynthesis, light energy and inorganic compounds are used to produce organic compounds -glucose- and release oxygen.

It occurs in chloroplasts and involves two stages: light-dependent and light-independent reactions.

• During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions. It occurs in the thylakoid membrane in the electron transporter chain.

• The light-independent reaction occurs in the Calvin cycle in the stroma. During this stage, carbon from CO2 is fixated, and sugar molecules are synthesized

Cellular respiration is the process through which cells use organic compounds to produce energy.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

1. Occurs in the presence of free oxygen.

2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

3. Respiration occurs in the mitochondria.

4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.

5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

1. Occurs in the absence of free oxygen

2. Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.

3. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.

4. Lactic fermentation produces lactic acid and 2 ATP

5. Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂

6. The whole anaerobic process occurs outside the mitochondria.

Photosynthesis is complementary to cellular respiration.

Answer:

photosynthesis

Explanation:

In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.

The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.

The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.

As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.
