Answer: Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person.
Based on the relationship between photosynthesis and CO2, explain why CO2 concentrations cycle over the course of a year?
Explanation:
the amount of CO2 found in the atmospheres varies over the course of a year how much of this variation happens because of the role of plants in the carbon cycle respiration occurs all the time but dominates during the colder months of the year resulting in higher CO2 levels in the atmosphere during those months.

Why do you think that dilating blood vessels will decrease temperature of the blood as well as decrease blood pressure?
Do you think if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions?
Answer:
yea
Explanation:
cause our climate conditions changes everyday depends on the atmosphere at that time so if there fire in a forest all the animals there have to adapt to the smoke.
Yes, if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions.
Why plants and animals will change their features?
Plants and animals are fundamentally different in many ways, but one of the most obvious is in how they deal with temperature.The climatic niche of a species reflects where it can live.A species with a wide climatic niche can range widely across many different conditions and may be especially resilient to climate change.Different sets of plant and animal species tend to occur at different elevations, which differ in temperature and precipitation.

When a box is set up like this it is really a representation of MEIOSIS. The "H" and "h" on the top of the box really represent . . .
A. all of the alleles present in each parent's non-sex cells.
B. the alleles each parent can contribute in their gametes.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
This observation forms the second principle of inheritance, the principle of segregation, which states that the two alleles for each gene are physically segregated when they are packaged into gametes, and each parent randomly contributes one allele for each gene to its offspring.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
When a box is set up like this it is really a representation of MEIOSIS. The "H" and "h" on the top of the box really represent the alleles each parent can contribute in their gametes.
Why were the high concentrations of DDT in the birds bodies?
Answer:
because chlorinated hydrocarbons accumulate in fatty tissues, when a ton of contaminated fishes is turned into 200 pounds of seabirds, most of the DDT from the numerous fishes ends up in relatively few birds. As a result, the birds have a higher level of contamination per pound than the fishes.

A construction company wants to trap pollutants in runoff at its sites. What should the company do?
O A.
Practice conservation tillage at the sites.
O B. Release beneficial insects,
such as spiders and ladybugs, at the sites.
O C. Plant grass and
lay straw at the sites.
O D. Plant trees at the sites.
Answer:
O C. Plant grass and lay straw at the sites.
Explanation:
Plant grass and lay straw at the sites are used by the company to trap pollutants at its sites because these plants reduce the runoff by absorbing most of the water and by absorbing water we can trap the pollutants present in that water. By trapping this industrial water, we can reduce water pollution that occurs due to this industrial waste and pollutants so planting grass and lay straw is the best way to trap pollutant.

Explain why the process of fertilization is the same for self-pollinating flowers and cross-pollinating flowers.
Answer:
Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Scientists have made estimates to the loss of biodiversity in the Mediterranean Sea over the next ten years due to various human-
influenced factors. The graph depicts the changes in biodiversity at present and in ten years (predicted). Which statement(s) below
are supported by the graph? Choose ALL that apply.
A)
Climate change will increase the loss of biodiversity at a greater rate than
pollution
Invasive species will have a greater impact in loss of biodiversity in ten
years than pollution
B)
C)
"Habitat degradation is and will continue to be the leading cause of
biodiversity loss in the Mediterranean Sea.
D)
The loss of biodiversity in the Mediterranean Sea will increase for nearly
every factor over the next ten years.
E)
Exploitation of species in the Mediterranean Sea will lead to the greatest
decline in biodiversity in the area in ten years.
Scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.
What is the significance of the loss of biodiversity in the Mediterranean?Biodiversity is low in almost every region of the world due to rapid urbanization, which has resulted in the rapid loss of plants and animals as well as a decline in their numbers due to habitat loss, and they are further impacted by climate change.
Hence, scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.

what is the part of endoplasmic reticulum without proteins attached?
Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer:
The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.
Explanation:
The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.
Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.
It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.
The energy required to get a reaction started is called activation energy.
