what biochemical function does an activated cdk perform?

Answer: FALSE

Explanation:

The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.

Parts of the nervous system includes:

--> Central Nervous System ( consists of the brain and spinal cord)

--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).

The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE

Living organisms control pH within their tissues. The reason for regulating pH is B. Many reactions can only happen at specific pH levels

The important for living organisms to maintain a stable pH within their tissues in order to ensure that all necessary reactions can occur. So one of the main reasons for pH regulation in living organisms is that many reactions can only occur at certain pH levels (Option B).

Additionally, pH can also affect osmosis (Option C) and the control of active transport (Option D), which are both important processes for maintaining homeostasis within the body. However, it is not necessary for all parts of the body to be kept at the same pH in order to survive (Option A), as different tissues and organs may have different optimal pH levels.

Answer:

Passive transport must occur to maintain homeostasis. Active transport must occur to get the needed nutrients in and out of the cell.

Explanation:

This barrier is an example of Behavioral isolation.

Behavioral isolation occurs when mismatches in mating traits (signals and/or preferences) prevent mating between two species/populations.

Members of a species cannot mate because of behavioural seclusion. It is a single mechanism among many that cause speciation. This mechanism causes behavioural divergence among population members over time. This keeps happening until they are unable to reproduce. They then split off into different types.

Behavioral isolation also stops recently diverged species from mating with each other. This prevents the two species from converging to form a new species.

(a) a stimulatory stimulus that prevents contraction of the knee extensor muscles

Explanation:

The interneuron in the spinal cord triggers answer choice an inhibitory stimulus that prevents contraction of the knee flexor muscles.(C)

When a stretch reflex is initiated, such as the knee-jerrk reflex, sensory neurons in the muscle spindle detect the stretch and send signals to the spinal cord.

These sensory neurons synapse directly onto motor neurons that control the knee extensor muscles, causing them to contract. Meanwhile, the sensory neurons also synapse onto interneurons in the spinal cord.

These interneurons inhibit the motor neurons controlling the knee flexor muscles, preventing them from contracting simultaneously. This inhibition allows for smooth, coordinated movement and is referred to as reciprocal inhibition.(C)

The risk premium of L2 is $1,966.

To calculate the risk premium, we need to compare the expected utility of the certain outcome (keeping the initial $20,701) with the expected utility of the lottery outcome.

For L1:

Expected utility = (0.5 * u(20,701 + 10,000)) + (0.5 * u(20,701 - 10,000))

For L2:

Expected utility = (0.85 * u(20,701 + 3,317)) + (0.15 * u(20,701 - 8,029))

Using the utility function u(x) = √x / 100, we can calculate the expected utility for each lottery.

For L1:

Expected utility = (0.5 * (√(20,701 + 10,000) / 100)) + (0.5 * (√(20,701 - 10,000) / 100))

For L2:

Expected utility = (0.85 * (√(20,701 + 3,317) / 100)) + (0.15 * (√(20,701 - 8,029) / 100))

To find the risk premium, we compare the expected utility of L2 with the expected utility of the certain outcome:

Risk premium = Expected utility of L2 - Expected utility of certain outcome

Expected utility of certain outcome = u(20,701)

Risk premium = Expected utility of L2 - u(20,701)

By evaluating the expressions, we find that the risk premium of L2 is approximately $1,966.

One of the key biological features to determine a Rajidae shark is the presence of thorn-like structures, known as dermal denticles, on their skin. These denticles give the skin a rough texture and are unique to sharks.

1. Dermal Denticles: Rajidae sharks possess dermal denticles, which are specialized scales that cover their skin. These denticles are composed of dentin, a hard substance similar to the material found in our teeth.

2. Thorn-like Structures: The dermal denticles in Rajidae sharks often have a thorn-like appearance. These structures protrude from the skin's surface and give the shark's skin a rough texture.

3. Location on the Body: The dermal denticles are distributed all over the body of Rajidae sharks, including the dorsal (upper) side, ventral (lower) side, and the fins.

4. Unique to Sharks: Dermal denticles are a characteristic feature found exclusively in sharks. They serve multiple purposes, including reducing drag in the water, protecting the shark's skin, and aiding in locomotion.

5. Identification: By examining the presence of dermal denticles and their thorn-like structures, researchers and experts can identify and differentiate Rajidae sharks from other species.

6. Additional Features: Apart from dermal denticles, other biological features like body shape, fin structure, and presence of specific reproductive organs can also be used to determine the exact species within the Rajidae family.

By considering these biological features, particularly the presence of thorn-like dermal denticles, scientists and enthusiasts can accurately identify a shark as belonging to the Rajidae family.

Explanation:

they could be a-symptomatic

After four hours you would have about 4096 bacteria.

Since the bacteria undergoes exponential growth, After each generation the population number doubles in size.

Hence, at the end of first 20 minutes we will have two bacteria.

at the end of 40 minutes we have 4 bacteria and at the end of one hour we have 8 bacteria and so on.

since the bacteria undergoes binary fission, a simple way to calculate the total number of bacteria is to divide the 4 hours in parts of 20.

In four hours the bacteria multiplies 12 times

hence, 2^12=4096.

In the sexual reproduction phase of the fungus life cycle, two haploid cells fuse to form a diploid zygote.

Sexual reproduction in fungi involves the fusion of two haploid cells, each with a single set of chromosomes, to form a diploid zygote with two sets of chromosomes. This zygote then undergoes meiosis to produce new haploid cells, which can grow and develop into new fungal individuals. The sexual reproduction phase in fungi is important for genetic recombination and the generation of genetic diversity. The exact details of the sexual reproduction phase can vary among different species of fungi, but it is typically characterized by the formation of specialized reproductive structures, such as fruiting bodies or hyphae, and the release of gametes or spores that can fuse with compatible partners.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology

If a population was void of predators, and the organisms were able to satisfy their needs, the population would experience exponential growth, option A.

Exponential growth is a type of population growth pattern in which the number of individuals in a population increases at an accelerating rate, leading to a J-shaped curve on a graph over time. In this type of growth, the rate of increase is proportional to the current population size, meaning that as the population gets larger, the rate of growth also gets larger.

This can occur in populations with unlimited resources and no limiting factors, such as predators or competition, but it is not sustainable in the long term as resources eventually become limited.
