Answer:

As one age, the bodies become subtle to cold temperatures. This is generally due to decline in the metabolic rate. As one age, the bodies lose the tendency of producing sufficient heat to sustain the usual temperature of 98.6 degrees. In addition to this, thinning of the skin is another thing, which may contribute to the feeling of cold in older individuals.  

With age, the physical tendency of the body declines, and the body does not function as it used to earlier. A decline in temperature can make the older adults very cold, even if they are dressed warmly. There are various researchers, which shows that older individuals exhibit low body temperatures in comparison to the younger ones.  

Some of the factors that can contribute to cold sensitivity in older adults are:  

1. Poor metabolic rate

2. Loss of elasticity of the blood vessels.  

3. Low blood pressure

4. Thinning of the fat layer underneath the skin

5. Physical issues and exposure to cold water

Which statement is not true?
Kamila [148]

Answer:

b) Reptiles, birds, and some mammals produce amniote eggs.

Explanation:

All the mammals produce amniotic eggs. An amniotic egg is an egg that has four extraembryonic membranes including amnion. Amnion is a fluid-filled sac that serves as a cushion and does not allow the egg to desiccate. Since mammals are land animals, they have amniotic eggs to prevent any damage to the embryo from desiccation and physical injury.

3.6 In mice, the allele C for colored fur is dominant over the allele c for white fur, and the allele V for normal behavior is d
KengaRu [80]

Answer:

a)  Parents Genotype should be (CC,Vv) and (cc,VV).

b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).

c) The genotypes of the parents are (Cc,Vv) and (cc,vv).

Explanation:

<h2>                                      (<u>a)</u> </h2>

Mating has occured between a normal colored mice whose genotype is C_,V_  and normal white  mice with genotype cc,V_. The offsprings are as follows :

1) normal mice produced 29 colored

2) 10 colored, waltzing progeny.

Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.

Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>

<h2>                                      (b)</h2>

In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv). </u>

<h2>                                      (<u>c)</u>  </h2>

In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv). </u>

How could change over a period of time lead to the development of a new species?
laiz [17]
Its natural selection. Due to genetic variations, some animals have traits more desirable then others. This animals will survive and reproduce better, over time creating a whole new species.
