The phrase that best describes the function of meiosis reduces the chromosome number by half and produces gametes. The correct option is D.
What is meiosis?Meiosis is the division of gametic or sex cells. This process occurs during reproduction. It completes in eight stages. It is divided into two parts. Meiosis I and meiosis II.
After meiosis, I, the daughter cells move directly into meiosis II without going through interphase or DNA replication. With the exception of the halving of the number of chromosomes, meiosis II resembles mitosis.
Because it contains the chromosomes of both parents, to make the number of chromosome-specific to humans, its numbers of chromosomes is reduced to make it 46.
Therefore, the correct option is D. reduces the chromosome number by half and produces gametes.

american society of hematology 2018 guidelines for management of venous thromboembolism: optimal management of anticoagulation therapy
Venous thromboembolism (VTE) is the third most common vascular disease. Medical inpatients, long-term care residents, persons with minor injuries, and long-distance travelers are at increased risk.
Strong recommendations included refraining from using direct oral anticoagulants while hospitalised, providing pharmacological VTE prophylaxis in acutely or critically ill inpatients at acceptable bleeding risk, and not extending pharmacological prophylaxis after hospital discharge.
Mechanical prophylaxis was also strongly advised when bleeding risk was unacceptable. Conditional suggestions included refraining from routinely administering VTE prophylaxis to long-term care patients or outpatients with negligible VTE risk factors. Only if long-distance travellers are at a high risk for VTE, the panel conditionally approved the use of graded compression stockings or low-molecular-weight heparin.

How is cellular respiration is similar in both plants and animals?
Answer:
The cells in both plants and animals perform respiration. Carbon dioxide is also released into the atmosphere when fuels are burned, such as in automobiles or factories. Plants take in carbon dioxide and release oxygen through their leaves. Plants use a process called photosynthesis to make their own food.
Explanation:
Cellular respiration is similar in both plants and animals in that it converts glucose and oxygen into energy in the form of ATP, produces carbon dioxide and water as byproducts, and occurs in the mitochondria.
What is cellular respiration?Cellular respiration is a metabolic process that occurs in both plants and animals to convert the energy stored in food molecules into a form that cells can use, called adenosine triphosphate (ATP). In both plants and animals, cellular respiration occurs in the mitochondria and involves a series of chemical reactions, including glycolysis, the citric acid cycle, and the electron transport chain.
During these reactions, glucose and oxygen are consumed, and carbon dioxide and water are produced as waste products. The energy released in these reactions is used to generate ATP, which provides energy for the cell's activities. Additionally, both plants and animals use a similar process, called photosynthesis, to convert light energy into chemical energy.

3. Many pea plants have rounded pods, but some have flat pods because they are homozygous for a recessive
allele (d). A plant that is homozygous for the dominant allele and another plant that has flat pods are crossed. Two of
the offspring are then taken and they are crossed to produce more offspring (called F2 offspring). There are 200 F2
offspring plants. Predict the number that will have flat pods. Show all your working.
The proportion of offspring homozygous recessive for at least two of the three traits is 6 out of 16 total offspring. Then it becomes 3/8.
The genotype of each plant contributes to its phenotype. In this case, the phenotype is the appearance of that flower. A given genotype is said to be homozygous if it has two identical alleles, and heterozygous if the two alleles are different. The process of genotyping is called genotyping.
Wood Since there are offspring that are homozygous recessive for both traits, each parent must have at least one recessive allele for each trait. Thus, the white disc parent has the WwDd genotype, and the white sphere parent has the Wwdd genotype. A cross between a long-stemmed pea and a short-stemmed pea is an example of a monohybrid cross. Crossing the two produces heterozygous offspring.

As given in the question there are 200 F2 offspring,
So, number of flat pods will be =( 1/4) x 200
=50
In monohybrid cross, both the alleles ( R and r) are expressed in the F2 generation without any blending. Thus, the law of segregation is based on the fact that each gamete contain only one allele.
here,A monohybrid cross results in a phenotypic ratio of 3:1 (dominant to recessive), and a genotypic ratio of 1:2:1 (homozygous dominant to heterozygous to homozygous recessive).

Going from 300 to 2,829 species represents what percent (%) increase in species diversity? (Show your work.)
Answer:
843%
Explanation:
2,829-300= 2,529/300=8.43(100)= 843% Increase in species diversity after completing the survey.
The percent (%) increase in species diversity is 843%.
HOW TO CALCULATE PERCENTAGE INCREASE:
The percentage increase can be calculated by dividing the increment by the original number, then multiplying by 100.Increase = new value - original value
In this case, the number of species went from from 300 to 2,829 species. Hence, the increase is calculated as follows:2829 - 300
= 2529.
The percent increase is therefore;
= 2529/300 × 100
= 8.43 × 100
= 843%.
Therefore, the percent (%) increase in species diversity is 843%.

Edmond Locard founded the first police crime laboratory in 1910 in Lyon, France. It is impossible for criminals to flee a crime scene without leaving behind traces of evidence that can be used to identify them, according to Locard's "exchange principle."
This concept served as the foundation for the forensic sciences, a body of methods for collecting and analyzing physical evidence from crime scenes. The "Sherlock Holmes of France," French criminologist Edmond Locard, who founded forensic science, lived from 13 December 1877 to 4 May 1966. Every encounter leaves a trace, according to his formulation of the fundamental tenet of forensic science.In the field of research that examines fingerprints, and dactylography, Locard made significant contributions that are well known.Although Edmond Locard passed away in 1966, his exchange principle has had a significant impact on forensic science and is still widely cited today.Learn more about forensic science here:

Explain how groundwater overdraft occurs and its likely consequences.
Answer: Groundwater overdraft occurs when the groundwater resources are used up more quickly than they are replenished. Groundwater overdraft can occur for a period of time without noticeable consequences, but eventually the aquifer will not be able to keep up with the rate of use as its water storage is depleted. This leads to unproductive or even dried up wells.
Explanation:
The consequences of the overdraft of groundwater is the contamination and emptying of groundwater.
What causes the reduction of water in the water table?The reduction of water resources has been accompanied by a significant increase in their pollution, generated by the incorrect disposal of industrial waste, garbage, pesticides, and by their irrational use.
What are the risks of lowering the water table in a building?Cracks in the walls of neighboring buildings. Remove windows and doors from the square. Pipe and coating breaks. Sidewalks and floors in neighboring areas can sink.
With this information, we can conclude that the consequences of the overdraft of groundwater is the contamination and emptying of groundwater.
