Mark Brainliest please

Poikilothermic animals include types of vertebrate animals, specifically some fish, amphibians, and reptiles, as well as many invertebrate animals.

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. This is why most reptiles are found in hot or warm climates. Reptiles often bask in the sun to get warm.

Both reptiles and amphibians are poikilothermic, which means that they cannot regulate their own body temperatures internally as birds and mammals do.

Marysya12 [62]
The answers are shown below:
In part A: 
            coefficient = 20
             variable = c
             constant = 35 & 23.50
In part B: 
           savings = 20 (3) +23.5+ 35+35+35 +35 +35 +35+35+35+35+35+35+35
           savings = $ 503.5
In part C:
            the new expression will be: 25c + 35 + 23.5

!!Help!! In dogs, the gene for fur color has two alleles. The dominant allele (F) codes for grey fur and the recessive allele (f
tatiyna

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.

Why is important the cell have a control sytem to regulate the timing of cell division?<br>​
-Dominant- [34]

Answer: It is important that cells have a "control system" because without it cells would either divide too fast or cause tumors to grow (cancer), or divide too slow and not be able to perform their cellular functions which is why the cells are controlled.

Nuclear envelope forms at each pole spindle dissolves chromosomes uncoil. True or False
Doss [256]

Answer:

True.

Explanation:

There are four phases which occur during karyokinesis, these are -

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

Telophase is the last phase of karyokinesis. The main events that occur during telophase are-

  • Uncoiling of chromosome occurs
  • Chromatin is formed
  • Spindle breaks down
  • Nuclear membrane or nuclear envelope if reformed

Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
