Answer:

your answer is a it forms a selective barrier by choosing what is good or bad for the cell.

Diffusing important molecules from outside to inside the cell and also discarding waste products from within the cell.

A rock lies in a river bed in a warm and wet climate, and the factor that would speed up its weathering is the flow of the water, which slows down considerably. That is option c.

In general, the rock weathering that is seen in the river beds is due to the water flowing, which leads to increased erosion and gives the slower moving water more time to dissolve minerals.

Hence, a rock lies in a river bed in a warm and wet climate, and the factor that would speed up its weathering is the flow of the water, which slows down considerably. That is option c.

Answer:

a receptive feild

Explanation:

The complex network of neurons built in response to an experience is most likely a memory.

Neurons are specialized cells that are the basic building blocks of the nervous system. They are responsible for receiving, processing, and transmitting information through electrical and chemical signals.

Memories are encoded in the brain by the formation and strengthening of neural connections between neurons, also known as synaptic plasticity.

When we experience something new, this process of synaptic plasticity is triggered and neurons form new connections or strengthen existing ones to encode the information.

Over time, these connections can become consolidated into long-term memory.

Therefore, when a person has an experience that causes a complex network of neurons to be built in their brain, it is most likely a memory.

Other chemicals that enter the circulation through the small intestine include the following:

Proteins' building components are amino acids.

The lipids' building components are fatty acids.

minerals and vitamins

The sperm of an angiosperm reach the egg via the pollen tube that grows from the pollen grain through the carpel tissues to the ovule.

Hence, the correct answer is option B.

Pollen is a fine powder that seed plants produce. Pollen grains (extremely reduced microgametophytes), which create male gametes, make up this substance (sperm cells). In the process of moving from the stamens to the pistil of flowering plants or from the male cone to the female cone of gymnosperms, gametophytes in pollen grains are shielded by a tough coating comprised of sporopollenin.

When pollen touches a pistil or female cone that is compatible with it, it germinates and creates a pollen tube that carries the sperm to the ovule that houses the female gametophyte. Pollen grains are so tiny that they must be magnified to be seen in detail. Paleoecology, palaeontology, archaeology, and forensics all benefit greatly from the study of pollen, which is known as palynology.

A. The difference between the two types of hydrogen bonds is that the bond between adenine and thymine is a double hydrogen bond and the one between cytosine and guanine is a triple hydrogen bond.

B. The double bond can only occure between adenine and thymine because they are a perfect match, it is its specific base partner. The same happens with guanine and cytosine, only them can form the triple bond.

This is called complementary base pairing

The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.

⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.

The allele Rh+ dominates over the allele Rh-.

Genotyopes and Phenotypes are as follows,

To express Rh-, a person must inherit two recessive alleles from their parents.

⇒ Color-blindness is an X-linked condition coded by a recessive allele.

As most sex-linked genes, it is transmitted together with the X chromosome.

The phenotype depends on the number of recessive alleles and the sex of the person.

Genotyopes and Phenotypes are as follows,

In this case, only one recessive allele is enough to express the affection.

In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.

Answer:

water

Explanation:

Beaker A is isotonic to cell A.

Some water is moving in and out of cell A.

Beaker C is hypotonic to cell C.

It is the tendency of water to move from the region of high to the region of low water.

Solutions that are isotonic to cells have the same solute concentration as the sap of the cells.

Solutions that are hypotonic to cells have lower solute concentrations than the sap of the cells.

Solutions that are hypertonic have higher solute concentrations than the sap of the cells.

The sap of cells A, B, and C have 0.9% NaCl. Beaker A has 0.9% NaCl, B has 3% NaCl, and beaker C has only distilled water.

Thus, beaker A is isotonic to cell A, beaker B is hypertonic to cell B, and beaker C is hypotonic to cell C.

The isotonicity of beaker A to cell A means that water would be in dynamic equilibrium between the cell and the beaker.

The sugar and phosphates do not provide the energy for dna replication

Sugar and phosphates do not provide the energy for DNA replication directly. Instead, the energy required for DNA replication comes from the hydrolysis of nucleoside triphosphates, which are building blocks of DNA.

The energy released by the hydrolysis of nucleoside triphosphates is used to drive the formation of phosphodiester bonds between the nucleotides in the growing DNA strand, which results in the replication of the DNA molecule.

The principle of uniformitarianism states about the modification in the planet surface over time through a constant and continuous process. It suggests that the change is the same in the present and past development.

The theory of uniformitarianism can be explained as:

The theory or the principle was given by the Scottish Geologist Hutton. It is a complete contrast to the theory of catastrophism.

According to the principles of this theory, the present is the mirror to the history and the geological evolutions of the past eras.

The principle states that the geological process is continuous and constant rather than being broken or discontinuous.

The metric system is a system of measurement that is utilized throughout the world. The fundamental units of the metric system are meter, gram, and liter. In this system, prefixes are used to represent measurements that are bigger or smaller than the fundamental units.

The prefix “kilo-,” for example, indicates a measurement that is a thousand times bigger than the fundamental unit. Lab Intro - The Metric System Exercise A - Measurement or Distance The metric system is used to measure length or distance.

The standard unit of length in the metric system is the meter, which is represented by the symbol “m.” The metric system is used to measure distances or lengths that vary from millimeters (mm) to kilometers (km).In order to determine measurements in the metric system, the fundamental units are combined with prefixes.

For example, one centimeter (cm) is equal to 1/100th of a meter, while one millimeter (mm) is equal to 1/1000th of a meter. One kilometer (km), on the other hand, is equal to a thousand meters (m).

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.
