When two different bird species temporarily occupy the same niche, they would most likely

Answers

When two different bird species temporarily occupy the same niche, they would most likely competewith each other.

What is the competition?

Is the struggle for limited resources between two organisms.

They compete with each other for food, shelter, space, a mate, etc.

Survival for the fittest

When two organisms temporarily occupy the same resources they will compete with each other.The most suitable organism will survive by nature. This is known as survival for the fittest.

Survival of the fittest states that organisms best adjusted to their environment are the most successful in surviving and reproducing. Competition is a major part of the survival of the fittest by Darwin's evolution theory.

Thus, we can state that competition will take place between 2 different bird species.

A plant leaf shows veins arising from a central thick vein to form a complicated network. Which type of venation does this plant exhibit? A. ParallelB. CrisscrossC. Reticulated

Answers

The type of venation which does the plant exhibit that the leaf shows veins arising from a central thick vein to form a complicated network is the (C.) Reticulated venation.
In reticulated venation, the veins here are arranged in a net-like pattern and are all interconnected. It is also the most common type of venation.

Answer:

C. Reticulated

Explanation:

In reticulated venation there is a central thick vein in the leaf and from there other little veins that form a net flow to the different parts of the leaf, that is called REticulated venation, it often happens that the central vein is located in the middle of the leaf and are easily spotted because that central vein creates a leaf that is two very similar halfs.

Which of the following is a requirement for a population to be in Hardy-Weinberg equilibrium? A.Immigration must outpace emigration. B.One allele must provide a benefit.
C.No mutation can take place.
D.The population must be very small.

Answers

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection.

The correct answer is C.No mutation can take place.

What are the 5 Hardy-Weinberg rules?

A low rate of mutations would help keep a population in equilibrium. The five assumptions of Hardy-Weinberg equilibrium are:

  • large population size,
  • no natural selection
  • no mutation rate
  • no genetic drift
  • random mating

What conditions are required for the Hardy-Weinberg model to apply?

No gene flow can occur to increase variability in the gene pool. A very large population size is required to ensure allele frequency is not changed through genetic drift. Mating must be random in the population. Natural selection must not occur to alter gene frequencies.

The best way to "untie" a male and female after the male has ejaculated is to? A. Pour warm water on them.
B. Gently pull them apart.
C. Do nothing until it happens naturally.
D. Pour cold water on them.

Answers

"Do nothing until it happens naturally" is the one among the following choices given in the question is the best way to "untie" a male and female after the male has ejaculated. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer helped you.

Answer: C. Do nothing until it happens naturally.

Explanation:

Animal husbandry involves the culturing, feeding and facilitating the breeding in animals. Breeding or reproduction is the important process as it is likely to increase the population of the animals which are kept for culture.

While sexual intercourse between the animals it is required that these animals are not untie forcefully instead they will separate on their own naturally. As forceful separation by pouring warm water, gently pulling apart and pouring cold water can harm the animals, may cause injury to any one of the mates, may generate shock which can affect the breeding ability of the two mates.
