You can infer there is a big population of sierra leone
As of 2013 the population of sierra leone is 6.092 million and is increasing.
Answer: Yes
Explanation:
Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others. When the resources are available in surplus then the population of a species increases exponentially but declines when resources become scarce. The human population is increasing tremendously all over the world this is supported by the resources like food, water, fossil fuels, air, minerals, and others. But some of these resources are decreasing due to overuse and may not be available in future to sustain the future generation.
Answer:
All the options are correct regarding hypothalamus.
Explanation:
The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.
This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.
Hypothalamus also has regulated anterior pituitary hormone secretion. Thus it controls the endocrine secretion of pituitary glands.
This plays an important role in hunger and thirst. The feeding habits like the licking of lips, swallowing, and salivating by seeing delicious foods is due to hypothalamic activities.
The behavioral activities of individuals influenced by the hypothalamus. It is worked along with the limbic system of the brain. The behavioral activities include fear, punishment and sexual desire.
Answer:
SER, they are capable of synthesizing testosterone of Adrenocortical cells.
Explanation:
Adrenal smooth microsomal cells are enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.
<h3><u>Answer;</u></h3>
All four organisms have exactly the same components in their DNA, but it varies in number and sequence
<h3><u>Explanation;</u></h3>
- <em><u>DNA, known as deoxyribonucleic acid is a type of nucleic acid which is important to all living organisms as it helps store genetic information.</u></em>
- <em><u>All living organisms store their genetic information using DNA molecules or RNA molecules. Most organisms contains DNA that have similar components, however their DNA will differ in number and also the sequences. </u></em>
- <em><u>The similarity between the molecules of DNA indicates a common ancestry among organisms. </u></em>
