Answer:

Not well

Explanation:

A large prey population means there's plenty of food for predators, the predators are more likely to survive and reproduce A large predator population means that the prey population will start to fall as individuals are killed and eaten As the prey population falls, there is less food for predators, so they too decrease in numbers

In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

Vika [28.1K]

Answer:

Behavioral scientists that investigate and explain how factors such as genetics, neurobiology, and hormonal responses can influence psychopathology are using a <u>biological</u> perspective.

Explanation:

The biological perspective focuses on the effects of the body on behavior, feelings and thoughts. The study of the biological bases of behavior is a link between two disciplines: psychology and biology. In this sense, the biological perspective implies the study of the behavior and mental processes of the individuals attending to their biological components. The biological perspective, also called neurophysiological, assumes that the mental disorder is a disease, just like any other physical illness and that psychopathological alterations are caused by biological abnormalities, such alterations can be the result of genetic factors, metabolic or hormonal disorders, physical trauma among others. The alteration of the brain is the primary cause of the abnormal behavior.

Some organelles, such as the endoplasmic reticulum and Golgi bodies, have a large and folded structure. What is an advantage of

bekas [8.4K]

Answer:

Explanation:

In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.

mitochondria has two membrane,

It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.

The folds also enables a large surface area that makes chemical process to occur in an efficient way.
