Answer:
waxing crescent
Explanation:
Position 8 represents waxing crescent phase. It is observed after a new moon and can be observed until the first quarter of moon.
What are the phases of moon?The waxing and waning nature of the moon is responsible for its various phases. This is due to the fact that moon is the only natural satellite of the earth. It revolves around the earth in a fixed orbit.
As earth revolves around the sun, the sunlight that falls on moon makes us visble those parts. Thus, it appears that moon is changing its shape.
A lunar month which is of 29.5 days usually is contains four primary and four intermediate phases. It is described as: New moon, Waxing crescent moon, First quarter, Waxing gibbous moon, Full moon, Waning gibbous, Last quarter and Waning crescent moon.
These phases have specific time in which they can be observed in the sky. New moon is an exception, as no part of the moon is visible then.
The phases of the moon are therefore considered as astronomically important.

Explanation:
edge 2021
AB positive and O negative are considered as universal blood types. AB+ has no antibodies that can attack the antigens on the red blood cells of the other blood types. The correct option is A.
What is universal receiver?The people with AB+ blood group are called as the universal receivers. They can safely receive a blood transfusion using any other blood type. Having a universal blood type can save a life of yours or someone else in an emergency.
If you have an AB+ blood type, you have both A and B antigens. Since a person has all of the antigens that are possible, this blood type is the rarest. The AB+ blood type has a positive Rh factor, the recipient will not reject the blood. So it can get any type of blood.
AB type blood has no antibodies against type A or type B blood. So a person with AB blood can receive any type of blood.
Thus the correct option is A.

In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.
Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.

Hannah and Becca are fraternal twins. They are both athletic. Hannah is a swimmer, and Becca is a runner. Which sister would have denser bones?
Answers
According to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.
What is Bone density?Bone density may be characterized as a type of measurement that significantly involves the accumulation certain amount of minerals contained in a certain volume of bone. This measurement is generally used to find out and treat serious bone loss, called osteoporosis.
When an individual is practicing in a swimming pool constantly for a longer period of time, it is observed that his/her bone density must be increased as compared to those who are running or performing other types of athletic activities.
Therefore, according to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.

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
Answers
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.

the crops could become resistant to pests and insects through natural selection
the soil could become drought resistant due to the shallow root structure that would form
the crops could begin to change their genetic makeup due to mutations from the parent plants
Answers
Answer:
A
Explanation:
I hope this helps :)
The soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
What is Soil?Soil is also defined as earth or dirt which is a mixture of organic matter, minerals, gases, liquids and organisms which together support life. These are distinguished from silt by restricting the former term specifically to displaced soil.
It provides many important services for both people and the planet by putting food on our plates, purifying our water, protecting us from floods and combating drought. Soil is also important in combating climate change because it captures and stores large amounts of carbon. Without healthy soil there is no food security.
Whereas growing the same crop year after year reduces the availability of certain nutrients and depletes the soil. Monoculture leads to soil exhaustion when the soil becomes deficient in these nutrients.
Thus, the soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).

Answers
Answer:
dna could be used for food by bacteria
Explanation:
not a beneficial reason
All of the following reasons are beneficial for prokaryotes to take up foreign DNA except the use of DNA as food by bacteria. Thus, the correct option is A.
What is DNA uptake?DNA uptake is defined as the conversion of exogenous, DNase-sensitive DNA into a DNase-protected state inside a bacteria. In gram-negative bacteria, this DNA uptake can be achieved by crossing the outer membrane. By contrast, in gram-positive bacteria, DNA uptake is similar to gram-negative bacteria with passage across the cytoplasmic membrane.
The uptake of DNA in bacteria is beneficial as it helps in the production of recombinants that can be used for various purposes. The DNA uptake can be used for the repairing of damaged DNA and chromosomes in patients of genetic disorders.
New genes with different functions can be introduced in organisms like bacteria.
Therefore, the correct option is A.

Plasmodium is an organism with both sexual and asexual life cycles. Describe the most likely cause of a heritable phenotypic change in some members of a population of asexually reproducing organisms. Explain how repeated exposure of the artesunate-sensitive Plasmodium strain to increasing concentrations of artesunate led to the development of the artesunate-resistant Plasmodium strain.
Answers
Answer:
Mutation.
Explanation:
Mutation in the organism's DNA that is passed on to the offspring is that main cause of heritable phenotypic change in some members of a population that reproduces asexually. Repeated exposure of Plasmodium that is sensitive to artesunate strain to increasing dosage of artesunate led to the development of resistance in plasmodium because the genetic mutation occur in the plasmodium that provide resistance against artesunate.
A unicellular eukaryotic organism that infects and lives in insects and vertebrates as a parasite is called plasmodium. They are single-celled organisms that undergo both types of reproductive life cycles.
The mutation caused a heritable phenotypic change in some members of a population of certain type of reproducing organisms.
The mutation in the plasmodium strain can be explained as:Some organisms of certain reproducing type happened to be mutated causing a heritable phenotypic change in their offspring's. When the plasmodium strain was repeatedly exposed to artesunate which altered some of the species in becoming resistant instead of being sensitive.The increased dosage or exposure caused a mutation in some type of certain reproducing strains causing them to be resistant to the amount.Therefore, the mutation caused the heritable phenotypic change.
