When people fall ill, their immune system fights the disease and tries to restore the person to good health. Which disease is known to attack the human immune system leaving the body susceptible to various kinds of infection?A. Chicken PoxB. PneumoniaC. TuberculosisD. AID
Answer:
D. Aids
Explanation:
Aids is one of the most deadliest diseases in the world. When you contract aids, it's designed to infect the cells that try to destroy it, it's a whole zombie apocalypse in your body and you don't even know it.
It attacks and weakens the immune system, and our immune system defends our bodies against infections, but HIV is extremely strong and it over powers the system, I'm not sure if there's an immune system strong enough to fight HIV or aids.

A bat is a mammal even though it flies in air why
Answer:
Explanation:
Bats are classed as mammals, but as the only flying mammal, people often ask me why they are mammals and not birds. In this article, I look to find out whether they possess all the mammalian traits. Bats are mammals because they breathe air, give birth to live young, provide milk to their young, have fur, and are warm-blooded.

Answer:
Embryotic stem cell research benefits our society with the possibility of it helping various diseases and it only requires a small number of cells. The negatives of stem cell research are the cost and ethical controversary. To start, stem cell research could help with diseases like Alzheimer's and certain cancers like Parkinson's. Also since cells replicate incredibly fast, procedures wouldn't need many cells depending on the case. Stem cell research can vary in costs from about $5000 to $20,000 which for many people is difficult because stem cells are very temporary in many cases. Many groups of people don't agree with stem cell research since human embryos are destroyed in the process of harvesting embryonic cells and it is "potential life".

Answer:
yes
Explanation:
An analysis of fossil traits indicates that Archaeopteryx is not a bird at all. ... Archaeopteryx seemed to confirm Darwin's theories and has since become a key piece of evidence for the origin of birds, the transitional fossils debate, and confirmation of evolution.

uncontrolled cell division can lead to the formation of masses of cells that can remain in place called ____ tumors or ones that can move called ___ tumors
Answer:
Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called primary tumors or ones that can move called metastatic tumors.
Explanation:
The term primary tumor refers to the original tumor, a place where the tumor first appeared.
Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.
For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.

What are the lines in leaves
Answer:
Veins – The blackish lines in the leaf blade are called veins. The largest black line is the leaf's single “midvein,” running from the petiole to the leaf tip, the smaller blackish lines branching off the midvein are “secondary veins”
In corn, seeds may be starchy (S) or sweet (s). Cross two heterozygous starchy corn plants. Using a Punnett’s square, give the phenotypic ratio then state the proportion of offspring that would be expected to be sweet?
if we cross Ss with Ss on the punnet square we will get the gametes S and s for both parents
on top left we have SS since we combine the alleles S and S
on top right we have Ss since we combine the alleles S and s
on bottom left we have Ss since we combine the alleles S and s
on bottom right we have ss since we combine the alleles s and s
The phenotypic ratio starchy:sweet is 3:1
1:3 of the offspring will be sweet

What evidence do we have of Neanderthal intelligence?
Answer:
What's more, genetic evidence has shown that modern humans mated with Neanderthals before these individuals disappeared about 40,000 years ago. Many of us today still have 1 to 2 percent Neanderthal DNA, findings that suggest that modern humans who encountered these individuals saw them as people, too.

to ensure that a cell does not become too large
to replace damaged cells and tissues
to ensure all cells remain undifferentiated
Answer:
To ensure all cells remain undifferentiated.

Cells divide to produce more, replace damages, and ensure a cell does not become to large.
So the only remaining choice is this.
The majority of the human body is made up of molecules that contain H,
C, O, N, and P. In your own words why is a diet of only carbohydrates insufficient for long
term survival?
Answer:
In the absence of carbohydrates in the diet, your body will convert protein (or other non-carbohydrate substances) into glucose, so it's not just carbohydrates that can raise your blood sugar and insulin levels. If you consume more calories than you burn, you'll gain weight.

Explanation:
2. a) Describe the ways that energy is converted between forms during the light reactions. 2. a) Describe the ways that energy is converted between forms during the light reactions.
Answer:
Light energy is converted to chemical energy.
Please find the explanation below
Explanation:
Photosynthesis is a unique process that occurs in the cells of green plants and other autotrophic organisms. It is the process whereby they synthesize their food in form of carbohydrates (sugars). The photosynthetic process takes place in two stages namely: light dependent reaction and light-independent reactions.
The light dependent reaction or simply light reaction is the stage where light energy from the sun is harnessed by a pigment called CHLOROPHYLL and used to produce ATP needed to build glucose molecules in the next stage. Hence, via this process, the LIGHT ENERGY from the sun is converted to CHEMICAL ENERGY in ATP.

to breathe.
Plants, algae, and cyanobacteria all release oxygen as waste that animals use to breath.
What are cyanobacteria?Cyanobacteria are the type of bacteria which comes in the category of microorganisms and they are related to the bacteria they are not plants still they are performing the process of photosynthesis. The type of cyanobacteria is blue green algae.
Cyanophyta is the another name of cyanobacteria and they are from the phylum Gram-negative bacteria that used to obtain the energy that is utilized in the process of photosynthesis. The name of the cyanobacteria is depend upon its color and the common name of the cyanobacteria is blue-green algae.
Generally, there are five main types of cyanobacteria and these are named on the basis of their toxicity and they are named as Anabaena Flosaque, Microcystis aeruginosa, Aphanizomenon flosaquae, and the last one is Nodularia species.
Therefore, Plants, algae, and cyanobacteria all release oxygen as waste that animals use to breath.

the cells were kept in a dilute solution. they were then transferred to distilled water. explain what will happen to each of these two cells when they are placed into distilled water.
When you place the animal cell in distilled water, because distilled water is a hypotonic solution(has a lower concentration than the cytoplasm). Water will diffuse inside the cell through osmosis. This will cause the cell to swell and eventually burst.
When you place the plant cell in the distilled water. The water will diffuse inside the cell, the water will build up inside the vacuole and turgor pressure will appear. The cell won't be able to burst because the cell wall prevents it.
18. During meiosis, homologous chromosomes exchange genetic material. This exchange of
genetic material -
A. increases the genetic variation
B. reduces the diploid number to the haploid number
C. increases the haploid
number to the diploid number
D. reduces the probability of mutations
A. increases the genetic variation
that's why individuals don't look like their partents. This process is called crossing-over
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material - A. increases the genetic variation.
During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in recombination of the genetic material and creates a new genetic combination. This results in variations, which can be beneficial to the offspring providing a better survival advantage.So, the correct answer is Crossing over produces new combinations of genes on alleles, increasing genetic variation.
