Answer:
The correct answer is - d. Anopheles.
Explanation:
Culex, a species off mosquitoes known as the vector for many viral and parasitic diseases such as elephantiasis, that spread the disease and to one person to other.
In America culex is the main vector for Lymphatic filariasis or elephantiasis that is caused by a parasite. However in Africa Anopheles is the main mosquitoes causes Lymphatic filariasis or elephantiasis in people of the area.
White blood cells (WBCs) are more resistant to lysis than red blood cells (RBCs). When looking at a sample of blood for WBCs, what could you do to reduce interference from RBCs? Group of answer choices Mix the blood in a hypotonic solution, which will cause the RBCs to lyse. Mix the blood in a hypertonic solution, which will cause the RBCs to lyse. Mix the blood in a salty solution to cause the RBCs to lyse. Mix the blood in an isotonic solution and allow the WBCs to float to the top.
Answer:
The correct option is this: MIX THE BLOOD IN A HYPOTONIC SOLUTION WHICH WILL CAUSE THE RED BLOOD CELL TO LYSE.
In order to reduce interference from red blood cell, mix the blood sample with a hypotonic solution. Because the red blood cells has more solute concentration, water from the hypotonic solution will enter into its cells and with time the cells will burst since they do not have much resistance against lysis. The bursting of the cells will eliminate the red blood cells and leave you with white blood cell to work with.

Which type of selection is also known as diversifying selection because it tends to favor the survival of two or more different phenotypes in a heterogeneous environment
Answer:
Disruptive selection.
Explanation:
Disruptive selection is also called diversifying selection because it favor the survival of two or more different types of phenotypes in a particular environment. Disruptive selection describes changes in population in which extreme values for a trait are favored whereas the intermediate values are less favored. Due to the increase the variance of the trait which leads to the division of population into two distinct groups.
Darker skin in equatorial environments is adaptive because it prevents ____________ deficiencies, which cause _____________ in newborns.
Answer:
Vitamin D
Rickets
Explanation:
Lack of vitamin D causes rickets
Darker skin in equatorial environments is adaptive because it prevents vitamin D deficiencies, which cause Rickets in newborns.
What determines skin color?The pigment melanin is by far the most important factor that determines the color of people's skin, although there are many other factors that play a role. People with darker skin have more melanin, which is the primary pigment responsible for their skin color. Melanocytes, which are cells found in the skin, produce melanin.
People who live closer to the equator typically have darker skin as a form of protection against the sun's ultraviolet (UV) rays. This is because excessive UV exposure can lower folic acid levels and lead to skin cancer.
Black people have more melanin in their skin than people with lighter skin, which affects the body's ability to synthesize vitamin D. People with lighter skin have less melanin in their skin.
Therefore, near equator more sunlight causes increased vitamin D production , preventing rickets in new born.

What are the possible phenotypes of the children if the mother has Type O blood and the father has type AB blood
Answer:
Type A
Type B
Explanation:
Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but are codominant. This means that the following genotypes will give rise to the phenotypes as follows:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, if a mother with Type O (ii) blood and a father with type AB (iAiB) blood are crossed, the following offsprings will be likely produced:
iAi, iAi, iBi, iBi
iAi - type A
iBi - type B
Hence, the possible phenotypes of the children will be type A and type B blood.

The doubling time of a bacterium was measured at two different temperatures. Which results would be expected of a thermophile
Answer:
Increase in high temperature.
Explanation:
The population of the thermophile bacteria increase at high temperature as compared to other bacteria at high temperature because thermophile bacteria needs high temperature for growth and survival. Thermophile bacteria that flourish at relatively high temperatures ranging from 41 to 122 °C (106 and 252 °F) so we can conclude that the thermophile bacteria increase in population in the high temperature conditions.
Which hypothetical antibiotic would treat bacterial infections by interfering with bacterial reproduction
Answer:
bacteriostatic
Explanation:
Bacteriostatic is a type of antibiotic that can treat bacterial infections because the this chemical attack on the reproductive system of bacteria so that they can't multiply or increase in number. This Bacteriostatic is a biological or chemical agent that prevent bacteria from reproducing by not directly killing them. Depending on their application, bacteriostatic is considered as antibiotics and disinfectants.

Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years and is the largest contributor to climate change?
Answer:
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.
Explanation:
Why does it matter?
As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.
Answer: carbon dioxide

At each ______ foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the ______.
Answer:
At each intervertebral foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the spinal nerves.
Explanation:
The dura mater is the outermost meninge. It is around the spinal cord and the brain, and it protects these organs. In the spine, the dura mater extends between the intervertebral foramen. The intervertebral foramina are the areas between each vertebra that have spinal nerve projections. In these areas, the dura mater extends to seclude the space where the spinal cord is since it fusses with the tissue that is around each spinal nerve to stop the entrance of any pathogen to the spinal canal, which is the space that contains the spinal cord.
