As a result of meiosis:one diploid cell has divided twice forming 4 haploid cells.gametes are producedgenetic variation increases.All of these choices are correct
Answers
Meiosis is a process of cell reproduction and like mitosis consists of prophase, metaphase, anaphase and telophase. However, unlike mitosis, meiosis performs these processes twice, so it has prophase 2, metaphase 2, anaphase 2 and telophase 2.
Importantly, between meiosis 1 and meiosis 2 no replication of genetic material occurs, so at the end of telophase 2, 4 haploid daughter cells will be obtained, which means that they will have only half of the genetic material.
Because of this, this is a process that is used for the formation of gametes (sperm and eggs).
In addition to this, during meiosis 1 homologous chromosomes exchange their genetic material in a process called crossing-over.
Therefore, the answer is D, all options are correct.

Answers
Answer:
a. is an example of ii) osmosis.
b. is an example of i) diffusion
c. is an example of i) diffusion.
d. This is an example of i) diffusion
Explanation:
a. This is an example of ii) osmosis. Water moves from a dilute solution (low solute concentration) in the soil into the cells in a plant's roots (higher solute concentration) through osmosis. The movement of water occurs across a semipermeable membrane, which allows water molecules to pass while restricting the passage of solutes.
b. This is an example of i) diffusion. Saliva flowing out of the salivary glands into the mouth involves the movement of solutes (salivary components) from an area of higher concentration (glands) to an area of lower concentration (mouth). This movement occurs due to diffusion, which is the natural tendency of particles to spread out and reach equilibrium.
c. This is an example of i) diffusion. The blue ink dropped into a glass of still water disperses throughout the water, coloring it blue. This dispersion occurs due to the random movement of ink particles, spreading from an area of higher concentration (spot of ink) to an area of lower concentration (water). It is an example of diffusion.
d. This is an example of i) diffusion. Carbon dioxide diffuses into a plant's leaves during photosynthesis. Carbon dioxide molecules move from an area of higher concentration (surrounding air or atmosphere) to an area of lower concentration (inside the leaf) through diffusion. The process of diffusion allows the plant to obtain the necessary carbon dioxide for photosynthesis.

What are fossil fuels?
Fossil fuels are those fuels which are obtained from the conversion of fossils of dead plants and animal which over a long period of time and under intense heat and pressure are converted to fuels.
Examples of fossil fuels are coal, natural gas and petroleum.
Fossil fuels mostly contain carbon which is released into the atmosphere in the form of carbon dioxide when these fuels are burned.
Therefore, fossil fuels increase the amount of free carbon in the global carbon cycle.

Do plants take in air with their roots?
Answers
Answer:
No
Explanation:
No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have a negative effect on aquatic species. The negative effects include:
Developmental dysfunctionGender imbalancesToxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.
The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female aquatic species such as reef fish.
Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

Vitamin D has many functions throughout the body. While severe deficiency directly leads to poor bone mineralization, resulting in rickets and osteomalacia, current research suggests that a deficit in vitamin D may be involved in the etiology of many disorders, including cardiovascular disease, respiratory infection, diabetes, infectious disease, and some cancers. Given what you know about the characteristics of a deficiency disease, which of the following would be considered a deficiency disease resulting from inadequate levels of vitamin D?
A. Osteomalacia
B. Rickets
C. Cardiovascular disease
D. Fatty liver
E. Type 2 diabetes

Answer:
Osteomalacia and rickets
Explanation:
Osteomalacia and rickets are very characteristic pathologies due to vitamin D deficiency. Both are the same, but the difference between them is age and the morbidity they generate, rickets is in children, therefore the sequelae are much worse because they drag these bone disorders throughout his life, causing his morbidity to be high.
Meanwhile, osteomalacia is in adults, many adults because they cannot sunbathe, find themselves facing sedentary lives or even living in few areas with the sun, are affected by this pathology.

Glycogen is a branched polymer and the storage form of carbohydrates in the human body.
The main storage sites are the liver and skeletal muscle. Glycogen is the main source of energy during fasting or between meals. Glycogen provides energy for up to 18 hours, after which energy needs are met by the oxidation of fatty acids.
The 2 metabolic pathways of glycogen are glycogenesis (glycogen synthesis) and glycogenolysis (glycogen breakdown). The main regulatory enzymes in these processes are glycogen synthase (in glycogenesis) and glycogen phosphorylase (in glycogenolysis).
These pathways occur as a function of the energy needs of the cells, generally modulated by hormonal and allosteric regulators.
Abnormal accumulation of glycogen occurs with enzyme deficiencies, which cause different types of glycogen storage disorders.
