THIS IS THE THIRD ASKING thIS QUESTION
only number 3
Answer:
3.) The giraffe has adapted by it's neck length increasing to reach the branches
4.) Biotic factors
Explanation:
QUESTION 3: Due to the leaves growing towards the top of tree rather than around, the giraffes neck length impacts the access to the leaves, so they have adapted by increasing their neck length.
QUESTION 4: Giraffes and trees are both living things, therefore they are biotic factors.
The _____ controls what enters and leaves the cell.
1.mitochondria
2.endoplasmic reticulum
3.nucleus
4.cell membrane

Which of these statements best describes the connection between biodiversity and evolution?
The more biodiversity an area has, the greater the chances of new species arising.
If biodiversity is high, then more predation will take place, preventing species from evolving,
Without a lot of biodiversity, organisms are more likely to survive, so they have more time to adapt.
Evolution depends upon low biodiversity to keep population sizes down, which increases numbers of genes.
Answer:
Without a lot of biodiversity, organisms are more likely to survive, so they have more time to adapt.

PLEASE SOMEONE DO THIS, The questions are:
1) Mention 5 different types of pathogens and mention within each type one harmful and one harmless example.
2) What is the main difference between nonspecific and specific immune responses? Mention 3 examples for each of them.
3) Mention 6 examples of white blood cells. When blood is centrifuged, where do white blood cells are found?
4) Be able to mention all of the steps involved in humoral and cell mediated immunity. After mentioning the 4 steps, explain what is the reason every step is happening. Have in mind that you need to explain 8 steps, since there are 4 per mechanism.

What type of current is most likely found in the deeper ocean depths, and why?
Answer:
The Explanation for the Question:
Deep ocean currents, a.k.a Thermohaline Circulation, are caused by the sinking and the transportation of large masses of cold water, which is guided by density inclines due to contrasts in temperature and salinity. Deep currents are also caused by the earth's rotaion.

Answer the following questions in complete sentences in the space provided:
1. Why does cell division take place in single-celled organisms?
2. What occurs in a cell when it is not undergoing cell division?
3. How do chromosomes change before cell division?
4. What is mitosis?
5. Why doesn’t mitosis occur in prokaryotes?
6. What would happen if DNA did not duplicate during interphase?
7. What is cytokinesis and when does it happen?
8. During what phase of mitosis do the chromosomes line up?
9. When do the chromosomes condense and become visible under a microscope? 10. What happens to the chromosomes during anaphase?
11. Sometimes a cell inaccurately duplicated its DNA, and the resulting cells are not identical. What effects might such a change have on the organism?
Answer:
1.All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences. Single-celled organisms use cell division as their method of reproduction.
2.What happens to cells that "decide" not to divide? If the decision is to not divide, the cell goes into a quiescent, or nondividing state, called G0 (G zero).
3.Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope (Figure 1).
4.Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
5.In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. This type of cell division is called binary fission.
6.If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
7.Cytokinesisis the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.
8.Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
9.During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.
11.When Replication Errors Become Mutations. Incorrectly paired nucleotides that still remain following mismatch repair become permanent mutations after the next cell division. This is because once such mistakes are established, the cell no longer recognizes them as errors.

Photosynthesis is to oxygen as:
A. Oxygen is to carbon dioxide
B. Cellular respiration is to carbon dioxide
C. Cellular respiration is to oxygen
D. Cellular respiration is to enzymes
Answer: It is C but if it was multiple choice it would be both B and C.
Explanation: Allow me to explain my reasoning. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). And allow me to explain the answer C. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Therefore, it can be both B and C if it was multiple choice. Thank you for your time.
Photosynthesis is to oxygen as Cellular respiration is to carbon dioxide. Thus option B is correct.
what is photosynthesis ?The process in which sunlight energy is used by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast which has its own DNA, genes and hence can synthesize their own proteins, photosynthestic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.
plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts
Antennae is made up of 100 to 5000 pigment molecules that capture light energy from the sun in the form of photons, Reaction Centers where photosynthesis occur.

Which statement explains why secondary succession is generally more rapid than primary succession?
An area of secondary succession has never been colonized.
There are no competing organisms in secondary succession.
The soil is already present at the start of secondary succession.
Pioneer species in secondary succession include bacteria.
Answer:
The soil is already present at the start of secondary succession.
Explanation:
Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species.

Which one of these happens in an 11 year cycle?
Coronal Mass Ejection
Prominences
Solar Flares
Sun Spots
Answer:Solar flares
Explanation:
Answer: Solar Flares
Explanation: The Sun's magnetic field goes through a cycle, called the solar cycle or known as solar flares. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.
