Which of the following statements is a correct explanation for the observation that all offspring exhibit a phenotype for a part
bearhunter [10]

Answer:

D) Neither of the parental genes is dominate over the other.

Explanation:

<em>Since the trait on the offspring is a mixture from both parent, it means that neither of the alleles from both parents is completely dominant over the other. Instead, each of the alleles contributes equally to the trait of the offspring.</em>

This effectively explains the fact that each trait exhibited by offspring is a blend of the traits from the two parents.

The correct option is D.

Two environmental changes are described below: Environmental change 1: Many small tree saplings are competing for sunlight on th
lilavasa [31]

Answer:

Both statements are true

Explanation:

Many small tree saplings are competing for sunlight on the forest floor because tree saplings in forest floors are often deprived of adequate light as a result of the shade created by bigger trees in the forest. <em>Hence, the saplings jostle for light in order to effectively carry out light-requiring physiological activities such as photosynthesis and chlorophyll synthesis.</em>

The West Nile virus a virus that <em>generally affects the central nervous systems of birds - the primary host. It is transmitted from one bird to another through contact and by a vector - the mosquito</em>. The virus is also capable of being contracted by humans where it causes fatal neurological disorders.

Describe an experiment to investigate the effect of training on subjects ability to run faster without respire get anaerobically
Zinaida [17]
A runner HAS to use the anaerobic respiration process,first we need to know the difference between anaerobic respiration and aeorobic respiration 

<span>Anaerobic respiration is done by burning glucose directly without the presence of oxygen giving out lactic acid and energy </span>
<span>Aerobic respiration is done by burning glucose and oxygen giving out water + engergy + Co2 </span>

<span>1.) Take a stop-watch </span>
<span>2.) Take TWO or more runners </span>
<span>3.) Unlike Olympic race match ask ONE of the runners to run their fastes and the others to GRADUALLY speed up </span>
<span>4.) make the runners breath hard for air </span>
<span>5.) after finish line </span>
<span>6.) do a test of Lactic through urin test or use Lactometer (don't ask me how to use it 'cause I don't know lol) </span>
<span>7.) check the concerntration </span>
<span>8.) whoever has the LOWEST concerntration,take that runner time for running and meter to find speed you'll be able to spot out who has used aerobic respiration during the race</span>

Red flower color is dominant to white flower color in red roses.what is the expected result of a cross between two heterozygous
OlgaM077 [116]
Heterozygous parents would have the genotype Rr. In a punnett square, this would show a result of 25% homozygous dominant (RR) offspring, 25% homozygous recessive (rr) offspring, and 50% heterozygous (Rr) offspring.
(I attempted to simulate a punnett square with the text)

    <u>  </u><u>R         r

<u />R| RR  |  Rr
