What effect does malnutrition during critical times of development in pregnancy have on the fetus?

Biology

Naya [18.7K]2 years ago
7 0
The effect that malnutrition have on the fetus during critical development in pregnancy is that the impairment  of the development of an organ is irreversible. Maternal malnutrition can adversely affect the division and replication of cells in the embryo at this stage, impairing its development. The effects of malnutrition during critical periods of pregnancy are seen in defects of the nervous system of the embryo, poor dental health among other effects.

In the sweet pea crossing experiment by Bateson and Punnet, the F2 generation had many more offspring with the phenotypes of pur
gizmo_the_mogwai [7]

Answer:

The F2 generation can be explained because the alleles for flower colour and pollen shape are linked.

Explanation:

<em>When two alleles are linked on the same chromosome, there is a high tendency for the alleles to be inherited together. Consequently, the frequency of the alleles recombining in subsequent generations is low.</em>

This is what Bateson and Punnet observed. There exist a linkage between P and L alleles and also p and l alleles, thereby increasing their frequencies  of occurring together and decreasing the frequency of their recombination.

Thus, the F2 generation observed by Bateson and Punnet is due to linkage of alleles.

Which equation correctly shows the reactants and products of photosynthesis? A C6H12O6 + 6CO2 --&gt; 6O2 + 6H2O B C6H10O6 + 6O2
scZoUnD [109]

The right option is D 6CO2 + 6H2O --> C6H12O6 + 6O2

This equation shows that carbon dioxide and water are used with light energy to produce glucose sugar and oxygen gas.

Photosynthesis is a process by which plants and other autotrophs use energy from sunlight to produce nutrients from carbon dioxide and water. Plants absorb water through the roots, carbon dioxide from the air, and light energy from the Sun, to produce glucose and oxygen.

Axons from higher brain centers form motor tracts that descend from the brain into the white matter of the spinal cord and then
Alchen [17]

Motor output that is gotten from the spinal cord to skeletal muscles involves somatic motor neurons of the anterior gray horn. Many somatic motor neurons are regulated by the brain. Axons from higher brain centers form motor tracts that descend from the brain into white matter of spinal cord and then synapse with somatic motor neurons either directly or indirectly by first synapsing with interneurons that in turn synapse with somatic motor neurons.

Sensory receptors is known to detect sensory stimulus.

Sensory neurons often convey sensory input by nerve impulses through their axons. Their axon often start from sensory receptors into the spinal nerve and into posterior root.

From posterior root, axons of sensory neurons have 3 different choices of paths.

  • Axons of sensory neurons does start into the white matter of the spinal cord and moves up to brain as part of sensory tract.

  • Axons of sensory neurons sometimes do moves into the posterior gray horn and synapse with interneurons that has its axons extend into the white mater of spinal cord and thereafter moves to brain as sensory tract.

  • Axons of sensory neurons oftens moves into the posterior gray horn and synapse with interneurons which the synapse with somatic motor neurons.

Axons that is gotten from spinal cord often synapse with other motor neurons in PNS.
