The cells produced via meiosis are called gamete cells, such as sperm cells or egg cells. Hence option a is correct.
What is meiosis ?In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body or somatic cells in humans are diploid, meaning they have two sets of chromosomes one from each parent.
The egg and sperm that combine during fertilizations must be haploid, or having just one pair of chromosomes, in order to sustain this condition. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell. Meiosis I and Meiosis II are the names of the two meiotic divisions.
Each chromosome's DNA is copied during the S phase of the cell cycle, resulting in two identical sister chromatids that are kept together by sister chromatid cohesion before meiosis starts.

What caused the oxygen levels in Earth’s atmosphere to increase during the Precambrian time? Choose the correct answer.
Land plants evolved and released oxygen as they grew.
The chemical weathering of granite released large quantities of oxygen.
Oxygen dissolved in the ocean was released by osmosis into the atmosphere.
Cyanobacteria consumed carbon dioxide and released oxygen as a waste product.
The Precambrian era is said to have taken place during the early years of our planet. During this time, the levels of oxygen in the atmosphere were much greater than they are today.
This level of increased oxygen in the atmosphere is a direct result of the biological processes and the sheer number of certain organisms present in Precambrian-era oceans.
Though the options stated all depict ways in which oxygen entered the atmosphere during the Precambrian era, the increase of oxygen levels is credited to the cyanobacteria.
The cyanobacteria were among the few living organisms present on the Earth during this time. They are small algae that use photosynthesis to sustain themselves.
Photosynthesis is known to produce and release oxygen as a waste product. This and the vast number of cyanobacteria present at the time account for the increase in oxygen levels during this era.

What is the difference between a guard cell and a white blood cell?
Guard cells are found in plants and white blood cells are found in animals.
What are guard cells?Guard cells are specialised plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are created in pairs, with a stomatal orifice separating them. What are white blood cells?The immune system's white blood cells, also known as leukocytes or leucocytes, are responsible for defending the body against both infectious diseases and foreign invaders. All white blood cells are created and developed from hematopoietic stem cells, which are multipotent cells found in the bone marrow. All parts of the body, including the blood and lymphatic system, include leukocytes.Guard cells function to allow gaseous exchange and white blood cells are responsible for the functioning of the immune system.

When comparing data between two different groups,
A.
the middles of the data sets and the spreads around them should both be considered.
B.
the most frequently occurring values and the middle values should both be removed from the data sets.
C.
only the highest and lowest values of the data sets should be considered.
D.
only the average values of the data sets should be considered.
Answer: A. the middles of the data sets and the spreads around them should both be considered.
Explanation:
When comparing data from two different groups, the most frequently occurring values should not be removed because they are most representative of the data and so will be very important in comparing the data.
The highest and the lowest values should not be the only data considered, indeed those should be the of lower importance than the values in the middles as the highest and lowest can sometimes be outliers.
Averages are good for summaries but shouldn't be the only things considered. The correct answer is therefore the first option that the middles and the spreads around the middle should be considered as these are more indicative of the groups.

Patient 1 has Type ___ blood.
Answer:
A.
Explanation:
Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.

and
generations.
Answer:
The correct answer is - haploid gametophyte and diploid sporophyte.
Explanation:
All plant life cycle shows alternation of generation. A plant's cycle alternates between haploid and diploid generation. The haploid generation is called gametophytic generation whereas the sporophytic generation.
The multicellular haloid structure of plants called sporophytic generation and these undergo meiotic or reduction division to produce the spores. These spores give rise to a haploid multicellular structure called gametophytic generation.

Do your experiments suggest that mushrooms are decomposers (organisms that break organic matter down to simpler, inorganic matter)? Explain.
Answer:
Explanation:
As we know mushrooms help to decompose dead organisms, and it helps breaks down dead plants and or, dead animals so yes I would suggest that mushrooms are decomposers.
Mushrooms are decomposers because they are capable of breaking down dead and decaying organic matter into simpler and inorganic matter to synthesize their own food.
What are the advantages of Decomposers?Decomposers are only living forms that are capable of converting organic matter into inorganic one which is easily consumed by the roots of plants for their metabolism.
Mushrooms form a web of mycelium that expands deep into the soil to decompose dead organic matter with the help of their unique enzymes.
It also plays a key role in nutrient recycling and makes nutrients available to plants in inorganic forms.
Therefore, it is well described above.
