How are we able to tell from the results of this blood type test that this is 0+
Answer:
there's no test so... The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

List 7 facts about a meteoroid
Answer:
https://solarsystem.nasa.gov/asteroids-comets-and-meteors/meteors-and-meteorites/overview/?page=0&per_page=40&order=id+asc&search=&condition_1=meteor_shower%3Abody_type
Explanation:
Answer:A meteoroid is a chunk of space rock. If it burns up while entering the Earth’s atmosphere it’s called a meteor and if a piece lands, it’s called a meteorite.
Millions of meteoroids travel through the Earth’s atmosphere every day, but most are small and burned up quickly. Very few reach the ground.
When a meteoroid hits the atmosphere of the Earth, they can be travelling as fast as 130,000 mph (209,215 km).
The blast caused by the shockwaves of the Chelyabinsk meteor in Russia was picked up by infrasound sensors on the other side of the world. Below is a video of that meteor.
The buying and selling of meteorite pieces in South Africa is illegal.
A meteorite that is seen or detected as it lands are called “falls”, with those that are discovered later being referred to as “finds”.
Meteoroids more than 10 metres in diameter are classified as asteroids.
Of the 500 estimated meteorites that reach the ground every year, only five or six are recovered for scientists to study.

1. What percentage of puppies would have the same genotype as the
parents, Ww?
Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.
How do igneous rocks provide evidence about the Earth?
Answer:
pls mark brainlest The chemical composition of an igneous rock tells us about the origin of the magma, beginning with which type of rock melted within the earth to form the magma in the first place, and how deep in the earth the melting occurred. Once magma has formed inside the earth, its composition may be modified.
If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
a) true
b) false
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".

A strain of Drosophila known as dunce produces one-half the amount of cAMP phosphodiesterase found in wild-type flies, which causes a learning defect. Another strain of Drosophila known as rutabaga produces a defective adenylyl cyclase protein (one of the AC types expressed in most cells) and also causes a learning defect. A dunce - rutabaga double mutant fly has relatively normal learning. Explain these curious observations.
Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.

What is the role of a ribosome in protein production?
A. It is the site where amino acids join to tRNA molecules.
B. It is the site where mRNA codons and tRNA anticodons meet.
C. It is the site where a protein strand is folded into its correct shape.
D. It is the site where proteins are packaged and sent where they are needed.
Answer:
Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

Explain how you found out that Lucy has ADA-SCID
Answer:
The first part of finding out Lucy having ADA-SCID was when I realized there were no HIV proteins in her blood, getting rid of the possibility of her having HIV. Then, I realized she had a high number of Deoxyadenosine in her blood. This proves she has ADA-SCID because when the ADA doesn't work you find excess amounts of Deoxyadenosine in the blood.

All organisms that can synthesize their food by means of photosynthesis are heterotrophic.
B.
All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
C.
All organisms that cannot synthesize their food by means of photosynthesis are heterotrophic.
Answer:
B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
Explanation:
There are three ways for a plant to obtain their food, photosynthesis, chemosynthesis, and heterotrophic. Photosynthesis is when the plant makes it's own food. If it can not get it's food from chemosynthesis or photosynthesis, it has to be an heterotrophic plant. The answer to the question is B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
How does washing your hands with soap inactivate coronaviruses that may be on your hands?
Answer:
Soap has chemicals that kill bacteria
When you wash your hands with soap and water, you surround any microorganisms on your skin with soap molecules. The hydrophobic tails of the free-floating soap molecules attempt to evade water; in the process, they wedge themselves into the lipid envelopes of certain microbes and viruses, prying them apart.

All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?
a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.
Answer: b
Explanation:
Camels ears are lined with fur to keep out sand and other blowing matter
The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.
What camels are adaptations for heat and dehydration?Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.
Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.
Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

4.flowers and fruit
Answer:
2 is the right answer
Explanation:
they do not produce fruit or flowers think of a pine treee of a spruce tree
Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.
What are gymnosperms?A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
The Coniferophyta, Cycadophyta, Gingkophyta, and Gnetophyta are the four primary phyla that makeup gymnosperms. Conifers, which have needle-like leaves and thrive in arid, cold climates, are the most common gymnosperm.
Some examples of gymnosperms are ginkgo, pine, melinjo. sago palm, cedars, and spruces. Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.

Rachel drove 300 miles from her home to Philadelphia to visit her sister and then returned home a week later. At the end of the trip what was her displacement and distance traveled in that order
Answer:
The correct answer would be - zero miles, 600 miles.
Explanation:
She started from the same point and after the trip, she ended it on the same point in Philadelphia therefore the displacement is expected to be zero.
The distance she traveled would be 2 into 300 miles as she traveled to her sister and traveled back from there so
Distance = 2*300
= 600 miles.
Thus, the correct answer would be - 0 and 600 miles.

Explain how seasons are similar and different on your Uranus as compared to the Earth.
Answer:
Uranus, like Earth, has four seasons. ... For starters, the length of Uranus' seasons are different from ours. It takes Earth 365 days to orbit around the sun, but it takes Uranus 84 Earth-years, more or less. So Uranus' year is 84 Earth-years along, and each season on Uranus lasts 21 earthly years.
