Crossed extensor reflex is a

Answers

Answer 1

Answer:

The crossed extensor reflex is a type of motor response that occurs to tactile stimulation of a lower limb. This, like other reflexes, is an indication of the proper integration and development of the central nervous system.

Explanation:

Stimulation on one side of the body can produce, in addition to the ipsilateral response. The crossed extensor reflex is a type of motor response, reciprocal innervation is involved: the flexor muscles of the stimulated limb contract at the same time that the extensors of said limb are inhibited. Coupled with flexion of the stimulated limb, the reflex produces an opposite effect in the contralateral limb: the extensor muscles are activated and the flexors are inhibited, this cross-extension reflex increases postural support during withdrawal of the painful stimulus.

If a pet has to survive without your care, how would its diet change? Write your ideas on the lines below. Read about how organisms get food and energy in their environment

Answers

Answer:

rather than consuming "pet food" that contains all proper nutrients required your pet would being to scavenge for food wherever they could find it. Survival instincts would kick in and they would eat whatever they could find. Depending on food availability, loss of muscle mass is a possibility.  

Explanation:

If my pet is to survive without me, its diet will change. First of all, he will not get food, so how is it possible for a living being to survive without food. It will get skinny and starve to death after a few days.

What is Diet?

Diet is defined as the sum of food that is consumed by a person or other organism. The term diet refers to the use of a specific intake of nutrition for health or weight-management reasons. Humans are omnivores so, every culture and every individual has some food preferences or some food taboos.

It is essential for good health and nutrition protects you from many chronic non-communicable diseases like heart disease, diabetes and cancer. Eating a variety of foods and consuming less salt, sugar, and saturated and industrially produced trans-fats are important for a healthy diet.

State Charles' Law as shown in the graph above.
Identify the volume if the temperature is 330K.
Identify the temperature if the volume is 0.0022 m3

Answers

Answer:

I. When the temperature is 330K, the volume is 0.025 m³

II. When the volume is 0.0022 m³, the temperature is 300 K.

Explanation:

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] \frac {V}{T} = K[/tex]

[tex] \frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.

From the graph, we can deduce the following;

I. When the temperature is 330K, the volume is 0.025 m³

II. When the volume is 0.0022 m³, the temperature is 300 K.

Which of the following best explains the evolutionary basis of human skin color? two parents who are heterozygous for each of the alleles have a greater probability of having a child with medium skin than one with very light or very dark skin in a diverse population, the distribution of the trait will be a bell curve, so most people will fall in the middle the inheritance of the alleles from each parent is completely random but in a population there may be natural selective pressure from the environment to favor different levels of expression multiple genes and multiple alleles each have an additive effect on how intensely the trait is expressed.

Answers

Answer:

From the given Options, Option  C is correct.

the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression

Explanation:

The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.

The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option  C.

You want to build a house in an area with a maximum amount of species diversity. For building the house you have to clear up to 3/4th of the forest cover. How do you think this will affect the water runoff?

Answers

Answer:

The runoff will increases.

Explanation:

The runoff will be adversely affected if the 3/4th of the forest cover is removed because forest cover lowers the intensity of runoff by absorbing most of the water. The construction of house will increase the runoff due to little vegetative cover for the absorption of water and more water will runoff on the surface that will leads to flood condition in the lower elevated region of that area. The vegetative cover of the forest helps in preventing the flood condition by absorbing the runoff water.

Fruiting Bodies of Fungi The recognizable forms of fungal reproductive bodies, or fruiting bodies, encountered in nature vary structurally. Common forms of fungal fruiting bodies include trumpet, club fungus, bracket, cup fungus, gill fungus, bolete, puff ball, and stinkhorn. Close observation of fruiting body anatomy can lend clues during identification of a species. Differing species of fungi can appear similar, and it is never advised to eat a wild mushroom because poisonous varieties can resemble edible ones.

Answers

Answer to Question 1:

True

Explanation

As indicated in the passage, fruiting bodies of fungi differ structurally. However, different species can appear to be similar and often misleading thus creating the risk of food poisoning.

Question 2:

Many experiments require student-supplied items, such as _____.

1. Chicken

2. Fresh flowers

3. Distilled water

4. All of the Above.

Answer to Question 2:

The correct answer is 3.

Explanation

Water comes in varying degrees of purity. When water that contains other substrates or impurities is used for an experiment, it distorts the results and creates errors. So the scientist's ability to determine the root of a problem becomes enervated.

Using distilled water impurities removes the possibility of such an error. Distilled water is also used for cleaning laboratory equipment.

Answers

Answer:

That B-form DNA helices have a pitch of approximately 34 angstroms

Explanation:

Rosalind Franklin was an X-ray crystallographer whose work contributed to the discovery of the molecular structure of DNA molecule by Watson and Crick. B-form DNA is the most common form of DNA, which consists of a right-handed double helix. B-form DNA was discovered by Watson and Crick based on the X-ray diffraction image of DNA (popularly known as image 51) obtained by Franklin. The pitch refers to the distance after every 10 base pairs along the DNA helix for one complete double-helix turn. This distance in the B-DNA helix is 34 Ångströms (i.e., 3.4 nanometers).
