Predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth. C. Plants evolve chemical defenses and herbivores evolve ways to neutralize the chemicals. D. Insects evolve green wings to blend into the environment, and predators evolve better eyesight to find the prey. Explain why.

Answers

The statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.

Coevolution is an evolutionary process where two or more species evolve in a parallel manner.

Coevolution is caused by an evolutionary race between species.

In general, coevolution is caused by selective pressures between one taxonomic group on another.

In conclusion, the statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.

explain the effects of the production of large amounts of antidiuretic hormone in the human body​

Answers

Answer:

Antiuretic hormone is a hormone that performs functions related to the reabsorption of water molecules through of the kidneys and with the decrease in the amount of urine accumulated in the body. An excess of antiuretic hormone conditions a retention of water and the elimination of sodium in the urine

Explanation:

Antidiuretic hormone (ADH) participates in regulating the water balance in the body, controlling the amount of water reabsorbed by the kidneys after they have filtered waste from the blood. Excess ADH leads to increased water reabsorption in the collecting duct, with increased urinary osmolarity. If there is too much ADH, water is retained, blood volume increases and affect can lead to nausea, headaches, disorientation, lethargy and hyponatraemia (decreased sodium concentration in the blood).

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?

Answers

It would be amino acids.

One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

What is the significance of the nitrogen in the protein?

Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.

As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

Clematis C. Delphinium D. Ranunculus

Answers

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

Different metabolic pathways exist within the same species.
Different species have the same genetic code.

Answer:

1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

2. Anabolism  & Catabolism

3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.

4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

What is reflex arc?

A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.

The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

They recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.

What are Pattern recognition receptor molecules?

Pattern recognition receptor molecules detect pathogen-associated molecular patterns (PAMPs), which are structurally conserved components of pathogens such as bacteria, viruses, and fungi. These molecules are essential for the survival and function of the pathogen, and are not found in the host's cells.

By recognizing PAMPs, the immune system can quickly identify and respond to a wide range of potential pathogens, without needing to recognize every individual pathogen separately. Therefore, the receptors are effective because they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.
