The rate of population change in the population is -4%

This shows that the population decreased.

Population is defined as the total number of individuals of the same species found in a given place or habitat.

The population of individual species usually change over time.

The changes that occur in a population of individuals may be as a result of:

The rate of population change is calculated as follows:

Initial population = 100

Final population = 100 + (14 + 2 -20)

Final population = 96

Rate of change of population = (96 -100/100) * 100 %

Rate of change of population = -4%

The population decreased.

The statement is true because " If the right key fits into the right lock then the lock will open.

The action of an enzyme upon its substrate is described as a "lock and key" mechanism is totally false because the true statement about the lock and key model is defined as the " if the right key fits in the right lock then the lock will open due to the right key, otherwise the lock will not open. Similarly, if the right enzyme fits in the right substrate, the product is formed, otherwise not. This mechanism named as lock and key because the key represents the enzyme while the lock represents the substrate.

So we can conclude that If the correct enzyme attaches to the substrate then the reaction will speed up in the lock and key mechanism.

Cells take up larger molecules across the plasma membrane through a process called endocytosis, which involves the formation of vesicles that engulf the larger molecules and transport them into the cell.

Transmembrane proteins with channels allow the passage of very small molecules across the plasma membrane, but larger molecules require a different mechanism of uptake. One way that cells can take up larger molecules is through endocytosis, a process where the cell membrane invaginates to form a vesicle that engulfs the molecule and brings it into the cell.

There are different types of endocytosis, including phagocytosis (engulfment of solid particles), pinocytosis (engulfment of fluids), and receptor-mediated endocytosis (engulfment of specific molecules that bind to receptors on the cell surface). Once inside the cell, the vesicle can fuse with a lysosome, which contains enzymes that break down the molecule for use by the cell.

Answer:

Disulfide bridges, which aid in the formation of the protein's tertiary structure, require cysteine residues.

Explanation:

A singular peptide chain and protein secondary structural features make up a protein's three dimensional or tertiary structure. A protein's tertiary structure is controlled by side chain connections and bonding.

Disulfide bridges, which are created by cysteine, join the pieces of a polypeptide chain together. Regarding their fundamental structure, such fragments can frequently be found at great distances from one another. Therefore, a protein's three-dimensional form is its tertiary structure.

Disulfide bridges are crucial for keeping the protein's three-dimensional- dimensional or tertiary structure. In an oxidizing atmosphere, disulfide production is promoted, but in a reductive environment, this disulfide bridge might be destroyed.

WHAT MAKES CYSTEINE DIFFERENT?

since its side chain contains a highly reactive sulfhydryl component. As a result, cysteine occupies a unique location and cannot be taken by another amino acid because the disulfide bridges that cysteine residues create are a constant part of the core structure of proteins.

macroevolutionary

Explanation:

Environmental conditions has a great affect on the survival, growth and development of organisms. If the environmental conditions are suitable for the organism so it will increase in population while on the other hand, if the environmental conditions are against the organisms so the organisms extinct from that region. The emergence, growth, and extinction of a large class such as dinosaurs is an example of a macroevolutionary pattern. Macroevolution is defined as the evolution of groups larger than an individual species.

The conductance of the blood vessel is 4.91× 10-6 ohm⁻

Given, here the length of blood vessel, L = 10cm.and the diameter, D = 1mm or 0.1 cm

Then, radius is equals to 0.1/2 = 0.05cm

Now, we calculate cross sectional area, which equals to πr2

A=πr² = π(0.05)²

We know that , the resistivity of blood ties between 80 ohm cm to 240ohm cm.

Therefore, The average resistivity, ρ= 80+240/2ohm cm = 160ohm cm.

Now, we calculate the resistance of the blood by the formula,

R= ρ l/A

R= 160ohm cm × 10cm/ π × (0.05) 2

R= 1600/ 7.854× 103cm2

R= 203.72× 103 ohm.

Now, we caclulate conductance and we know that it is reciprocal of resistance.

So, The conductance is, G= 1/R

G= 1/203.72× 103 ohm.

G= 4.91× 10-6 ohm⁻

Any conductor, including a lightbulb, will block the flow of an electric current; this obstruction is known as electrical resistance and is represented by the letter R. Conductors emit heat when current flows through them because all materials have an electrical resistance.

Conductance is defines as the reciprocal of the electrical resistance . It is denoted by G and it’s unit is ohm- (ohm minus).

Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.

In which squares should the phrase “Green pods” appear?

1.A and D  2.B and E  3.A,C and D  4.A,B,C,D and E

Answer:

3.A,C and D

Explanation:

As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.

As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

Pea-like firmness of the facial lymph nodes might indicate an infection from adjacent teeth or infection from the upper lip. The Correct option is A

When there is an infection in the teeth or the upper lip, lymph nodes in the face and neck region will react and enlarge to fight the infection. The lymph nodes may feel firm and tender, giving a pea-like sensation. On the other hand, if the lymph nodes are normal, they would be soft and pliable.

Additionally, an infection from tonsils or other respiratory infections can also cause swelling of the lymph nodes in the neck region. However, this would not lead to pea-like firmness in the facial lymph nodes.

An example of a prey and predator that co-evolve due to the Red Queen Hypothesis is the cheetah (predator) and the impala (prey) in the African savannah. The impalas evolve to become faster and more agile, enabling them to outrun cheetahs.

The impalas develop longer legs, allowing for increased stride length and higher running speeds, as well as enhanced agility through improved coordination and quick directional changes. On the other hand, cheetahs develop longer, more muscular bodies to improve their acceleration and top speed. They also possess sharper claws for better grip during high-speed chases.

These changes occur because faster impalas have a higher likelihood of escaping predation, while faster cheetahs have a better chance of catching their prey. Thus, natural selection favors individuals within each species that possess advantageous traits, leading to the co-evolutionary chase between the predator and prey.

Yes, there is a communication system between the bacteria forming the biofilm that allows them to know when to detach or when to adhere.

This communication system is called quorum sensing. Quorum sensing is a communication system between bacteria. They communicate with each other by sending signals, which can be chemical or physical. Bacteria can also sense the density of their population by using quorum sensing.

The bacteria produce small molecules called autoinducers that they release into the environment. The concentration of these autoinducers increases as the population density of the bacteria increases. When the concentration of autoinducers reaches a specific threshold, the bacteria will begin to alter their behavior, including detaching or adhering from the biofilm. This allows the bacteria to act as a collective and coordinate their activities.

Answer:

38 chromosomes are in the red foxes DIPLOID skin cells

Explanation:

There are two principal types of cells in the organism:

Gametes are the product of germ cell division by meiosis, and they have only one set of chromosomes, n (19 in this example). Their destiny is to merge in the process of fecundation, during which a new diploid cell called the zygote emerges through fertilization. The zygote is a complete diploid cell that suffers successive mitosis and forms a new organism (a new fox in this case).

- So, through meiosis, the diploid germ cell (2n) produces four haploid cells (n) that are the gametes.

- Through fecundation or fertilization, two gametes (n) merge and produce a diploid cell (2n) that is the zygote.

If the red fox gamete has 19 chromosomes (haploid number n, the single set of chromosomes), it must merge with another gamete (coming from the other parent) with 19 chromosomes to form the zygote. The zygote is a diploid cell. The zygote will suffer many mitosis divisions to become a new fox.

To know the number of chromosomes in a skin cell, we need to duplicate the number of chromosomes in the gamete (19).
