A biologist sequences the DNA of two different organisms and identifies these two sequences:
Sequence 1: GTACCACATCGAAGGGTC
Sequence 2: GTACGACACCGAAAGTTC
What conclusion can the biologist draw about the two organisms based on the DNA fingerprinting?
A.They are closely related but different species.
B.They are the same species.
C. One organism evolved from the other.
D. They are not related at all.
The two DNA sequences of organisms represent that they are closely related but different species.
What do you mean by Species?Species may be characterized as a group of organisms that can reproduce naturally with one another and produce fertile offspring.
DNA fingerprinting is a technology that reveals the similarity between the DNA sequences of two or more organisms of the same or different species.
Both the sequence are very similar to one another, only a few bases are altered which signifies that they are closely related but belongs to different species.
Therefore, the two DNA sequences of organisms represent that they are closely related but different species.

The purpose of ______ is to pass a copy of a cell's gene to cells in the next generation. The purpose of ______ is to pass the parents' genes onto the next generation.
The purpose of reproductive cells is to pass a copy of a cell's genes to cells in the next generation. The purpose of somatic cells is to pass the parents' genes onto the next generation.
Reproductive cells are specialized cells involved in the process of sexual reproduction. In humans and many other organisms, reproductive cells include sperm cells in males and egg cells (or ova) in females. These cells are produced through a unique cell division process called meiosis, which reduces the number of chromosomes in half to create haploid cells.
Somatic cells make up the majority of an organism's body and are involved in various functions, such as growth, repair, and maintaining bodily functions. Unlike reproductive cells, somatic cells are diploid, containing two sets of chromosomes—one inherited from each parent. While somatic cells do not directly pass their genes to the next generation, they play a crucial

How might an environment be affected if humans introduce a new type of plant to the environment? A. The plant may compete with other plants for light. B. The plant may become another food source for animals. C. The plant may be poisonous and harmful to animals. D. all of these
Answer:
D. all of these
Explanation:
The reason is because all of the above are TRUE.
A. The plant may compete with other plants for light.
It feels like Plants and Trees are just stuff growing, but they actually compete with other plants, some don't do that much, but some do that, so that new plant may do it to get more light and might put more shade on other plants, which is dangerous for other plants.
B. The plant may become another food source for animals.
This is pretty normal, I mean, the thing here is that any plant is vulnerable to being eaten by an animal.
C. The plant may be poisonous and harmful to animals.
Yeah, like in choice B, the same thing, the plants are always Vulnerable to be eaten by hungry animals, and if an animal eats it... then it might get a disease or might just die.
So if these are all correct, then the answer HAS to be D. All of these
Answer:
D. All of these

Identify and explain the purpose of the 4 major components in the refrigeration cycle?.
Answer:
compressor
Compression is the first step in the refrigeration cycle, and a compressor is the piece of equipment that increases the pressure of the working gas. Refrigerant enters the compressor as low-pressure, low-temperature gas, and leaves the compressor as a high-pressure, high-temperature gas.
condenser
The condenser, or condenser coil, is one of two types of heat exchangers used in a basic refrigeration loop. This component is supplied with high-temperature high-pressure, vaporized refrigerant coming off the compressor. The condenser removes heat from the hot refrigerant vapor gas vapor until it condenses into a saturated liquid state, a.k.a. condensation.
The expansion device
the job of a system’s expansion device is the same - create a drop in pressure after the refrigerant leaves the condenser. This pressure drop will cause some of that refrigerant to quickly boil, creating a two-phase mixture.
This rapid phase change is called flashing, and it helps tee up the next piece of equipment in the circuit, the evaporator, to perform its intended function.
evaporator
The evaporator is the second heat exchanger in a standard refrigeration circuit, and like the condenser, it’s named for its basic function. It serves as the “business end” of a refrigeration cycle, given that it does what we expect air conditioning to do – absorb heat.
This happens when refrigerant enters the evaporator as a low temperature liquid at low pressure, and a fan forces air across the evaporator’s fins, cooling the air by absorbing the heat from the space in question into the refrigerant.

Which of the following phases ends just before cell division?
A. M phase
B. G1 phase
C. G2 phase
Answer:
C
Explanation:
The G2 phase ends just before cell division as it is considered as the last phase of the process of cell division. Thus, option C is correct.
What happens in different phase of cell cycle?In eukaryotic cells, the phases of the cell cycle are divided into two major phases, which are interphase and mitotic stage. During the mitotic stage, cell divides its DNA and cytoplasm into two equal parts, thereby forming two daughter cells.
Cell division is essential for organism growth, tissue repair, healing and regeneration, and reproduction. The process by which a parent cell divides into daughter cells is known as cell division. For both single-cell and multicellular organisms, cell division is essential. Cell division can directly increase the population of single-celled organisms like Amoeba or Paramecium.
Therefore, The G2 phase ends just before cell division as it is considered as the last phase of the process of cell division. Thus, option C is correct.

Mendel crossed pea plants dominant for two different traits (tall and green pods) with pea plants recessive for those same two traits (short and yellow pods). This cross resulted in pea plants that had combinations of all four traits (tall with green pods, tall with yellow pods, short with green pods, and short with yellow pods). Which law of inheritance best describes why this happens
The law of inheritance that explains such a pattern of trait inheritance is the law of independent assortment of genes.
Law of independent assortmentThe law states that characters are inherited independently from one another. In other words, the inheritance of trait 1 is totally independent of the inheritance of trait 2.
There are several exemptions to the law of independent assortment of genes. There have been cases of linkages and gene interactions such as pleiotropy.
