In the Sierra Nevada mountains of California there are many populations of the checkerspot butterfly, Euphydryas editha. You not

ice that females of one population (population A) lay their eggs near the tip of a plant’s stem. Females of another population in the same area (population B) lay their eggs at the base of the stem on a different type of plant. The young hatch out as caterpillars; they live on the host plant and eat its leaves. Is the information above a complete description of the butterflies’ niche?

Which of the following populations would be considered r-selected? Black Widow Spiders - they produce 1000s of offspring and few
belka [17]

Answer:

Option 1.

Explanation:

r-selected species may be defined as the species that has higher growth rate, shows less parental care and the rate of survival of the off spring is low as compared  with k selected species.

Black widow spiders have the ability to produce 1000 offspring. Their chances of survival are extremely low and only few species of black widow spiders survive. Hence, black widow spider is r-selected species.

Thus, the correct answer is option (1).

What is the difference from a control group and a control variable?
geniusboy [140]
A control variable is a scientific experiment in which the experimental element is unchanged throughout the experiment

a control group is a group in an experiment that does not receive the treatment by the researchers (untouched by them) and used to see the changes between the controlled group and that of the group that received the vial

Difference between chlorenchyma and parenchyma​
astraxan [27]

Answer:

Explanation:

Parenchyma

1. They have thin cell wall.

2. Their cell wall is made up of cellulose.

3. They are unspecialized tissues.

4. The are found in soft part of the plant.

5. They undergo photosynthesis and can stored the food and also play important role in gaseous exchange.

6. There are spaces between the cells.

Collecchyma.

1. They are thick cell walls.

2. Their cell walls are made up of cellulose and lectin.

3. They are specialized tissues

4. They are found in plants leaves and petioles.

5 The do not undergo photosynthesis but act to give mechanical support to plants.

6. They have little intercellular spaces.

Parenchyma and collecchyma are both tissues found in plants..

In a population of Mendel's garden peas, the frequency of the dominant A (yellow flower) allele is 80%. Let p represent the freq
DENIUS [597]

Answer:

If the frequency of the dominant allele in the pea population is 0.8, the genotype frequencies in the population would be 0.64 AA, 0.32 Aa, and 0.04 aa.

Explanation:

Hardy-Weinberg equation tells us that:

p2 + 2pq + q2

p2 is the frequency of AA plants

2pq is the frequency of Aa plants, and

q2 the frequency of aa individuals.

A allele in the population is 80%, the frequency is 0.8.

p represent the frequency of A allele. p is 0.8

Therefore calculating for q ( frequency of a allele).

p + q = 1.0

q = 1.0 − p

q = 1.0 − 0.8

q = 0.2

p = 0.8, q = 0.2.

Now we can calculate the predicted frequencies of the different genotypes, remembering that p2 is the frequency of the AA genotype, 2pq is the frequency of the Aa genotype, and q2 the frequency of aa genotype.

p2 = 0.8 x 0.8 = 0.64

2pq = 2 x 0.8 x 0.2 = 0.32

q2 = 0.2 x 0.2 = 0.04.

Thus, we would expect to see genotype frequencies of 0.64 AA, 0.32 Aa, and 0.04 aa in the pea plants.
