The correct answer is: Cross the green-pod plant with a yellow-pod plant.

Yellow-pod plant phenotype is known to be homozygous recessive. In this case, we would use test cross to determine whether there are any recessive alleles in the unknown.  The recessive homozygote (yellow-pod plant) will contribute an allele for the recessive characteristic to each offspring, the second allele (from the unknown genotype, green-pod plant) will determine the offspring's phenotype.

The parent cell is also making a copy of its DNA to share equally between the two daughter cells. The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells

Answer:

Based on the hypothesis, an increase in the ratio of Gi to Gs proteins coordinated signalling, would decrease cAMP concentration when GCPR binds to it, with the Gi function intact and able to oppose the Gs protein activation.

The microsporidian Brachiola gambiae parasitizes the mosquito Anopheles gambiae. Adult female mosquitoes must take blood meals f
aalyn [17]

Answer:

The correct answer is B. 1, 2, and 4

Explanation:

Option no 1 is true because before maturity, the mosquitoes will not be able to cause malaria and will be easier to kill.

Option no 2 is true because in order to ensure a safe control, the Brachiola gambiae shouldn't be dangerous to other animals or insects.

Option No 3 is not true because Mosquito larvae will contain the male larvae also. As the male larvae are not harmful, hence their growth shouldn't be stopped or they should not be killed.

Option No 4 is correct because before applying any controlling measures for a problem, it should always be kept in mind that it should not have negative effects on other food systems.

Answer No 5 is false because as the females Anopheles are harmful, they should be killed. The male Anopheles are not harmful hence, they should not be killed.

Hello. This question is incomplete. You forgot to attach the image that completes the question.

The image is attached below:

Answer:

A- Sensory Neuron

B- Spinal cord

C- Effector neuron

D - Brain

Explanation:

  1. Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
  2. Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
  3. Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
  4. Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.
