Answer:
two
Explanation:
The endocrine and central nervous systems are the major control systems for regulating homeostasis
Gravitational force pulls on each unit mass with a constant force resulting in a constant acceleration (an increase in speed of about 10 metres per second every second). ... This is said to be the 'weight' of the object (i.e. the downward force it exerts because gravitational force is acting on it).
Please give brainliest.
Answer:
3/4
Explanation:
If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.
<h3><u>Gene A</u></h3>
AA x Aa
- F1 genotypes: 1/2 AA, 1/2 Aa
- F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>
BB x bb
- F1 genotypes: 1 Bb
- F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>
Cc x Cc
- F1 genotypes: 1/4 CC, 2/4 Cc, 1/4 cc
- F1 phenotypes: 3/4 C, 1/4 cc
We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:
<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>
Answer:
Limiting variables include a low supply of food and lack of room. Limiting variables may reduce birth rates, increase death rates, or contribute to emigration. Limiting factors determine a population's carrying capacity. Recall that the population grows exponentially when there are no limiting factors.
