select all of the following processes that can cause changes in allele or genotype frequencies in populations.

Answers

Answer 1

A gene variant's incidence in a population is represented by the allele frequency. Alleles are different versions of a gene that share a chromosomal location, or genetic locus.

An allele frequency is computed by dividing the total number of copies of all the alleles at that specific genetic locus in the population by the number of times the allele of interest is observed in a population. The decimal, percentage, or fractional forms of allele frequencies are all acceptable. The genetic variety of a population is reflected in the allele frequencies. Allele frequency variations over time can be a sign of genetic drift or the introduction of novel mutations into the population.

During moderate intensity exercise, most of the ATP used for muscle contraction is formed by?​

Answers

Answer:

Aerobic cellular respiration

Explanation:

Aerobic cellular respiration is the process by which your cells generate energy (ATP) from glucose (sugar from food) and oxygen.  Since this exercise activity is only moderately intense, you are getting plenty of oxygen, and this is how your muscles will generate energy.

why do we need to broaden our understanding of biodiversity

Answers

Answer:

Biodiversity is the variety of different types of organisms in the world or a particular area or ecosystem which is found to be very desirable and significant. Different types of plants, animals, and other organisms all are included in biodiversity and each has its own role.

Biodiversity of a biosphere or a region affects all organisms found in it from microbes to large plants and animals. Biodiversity gives an idea about a biosphere as it helps in the sustainability of all life forms if there are higher species variety.

Human beings need to broaden the understanding and knowledge of biodiversity as it is one of the major aspects that affect life all organisms present on earth.

How do hydrogen bonds contribute to body temperature regulation?

Answers

Hydrogen bonds contribute to body temperature regulation by one of the properties of water called high heat capacity. The water's high heat capacity is caused by hydrogen bonding among water molecules. These hydrogen bonds are broken down when heat is absorbed causing water molecules to move freely. When the temperature of water decreases, hydrogen bonds are formed; thereby releasing a considerable amount of energy.

Answer: Hydrogen bonds contribute to homeostasis that is maintaining body temperature.

Explanation: The hydrogen bonds between water molecules give water the ability to hold heat better than many other bonds. Heat energy is first used to break Hydrogen bonds, leaving less heat energy to increase movement of the molecules which is necessary to increase temperature. This property helps maintain homeostasis.

Which statement is correct about the properties that define a particular kind of mineral?(1 point)

Answers

Rocks are constructed from minerals, which are also the building components of our world. They are specified as naturally occurring and crystalline (as used in mineralogy).

What are minerals?

solids comprised of inorganic materials rather than biological ones, indicating that they have an organized internal structure. For instance, the bismuth crystal in the image below was made in a lab and is not a mineral since it does not naturally exist in this form.

Each mineral has a unique chemical structure and content that sets it apart from other minerals of a similar type. In addition, they contain distinct physical characteristics that enable scientists to recognize them without the use of a microscope. Let's examine each of these distinctive physical characteristics of minerals and consider how they are used to classify them.

Phenotype of wild type, Octopus phenotype, Appropriate examples of a blunt phenotypic include. Recessive mutations are gene changes that only manifest as a phenotype in individuals who are homozygous.

Genetic changes known as recessive mutations only manifest as phenotypes in individuals who carry two copies of the mutant allele. This contrasts with dominant mutations, which result in a phenotype even when the mutant allele is present in a single copy. Only when both parents have the mutant gene may a recessive mutation be transferred from parent to offspring. There is a 25% possibility that a child born to two carriers of a recessive mutation will carry two copies of the mutant allele and manifest the corresponding trait. Genetic illnesses including cystic fibrosis, sickle cell anaemia, and other conditions can result from recessive mutations, which are significant for genetic study and have practical implications for human health and medicine.

Which of the following statements is TRUE regarding the relative sizes of the different individual cells? a) Staphylococcus aureus are larger than Saccharomyces cerevisiae. b) Bacillus subtilis are larger than Saccharomyces cerevisiae. c) Human blood cells are larger than Bacillus subtilis. d) Staphylococcus aureus are larger than human blood cells.

Answers

Answer:

c) Human blood cells are larger than Bacillus subtilis.

Explanation:

Eukaryotes are typically much larger than prokaryotes. Prokaryotes vary in size from cells as small as about 0.2 mm in diameter to those more than 700 mm in diameter.

Bacillus subtilis, which are rod-shaped, are 4–10 micrometers (μm) long and 0.25–1.0 μm in diameter.

Staphylococcus aureus, which are spheres, are up to 1 μm in diameter.

Yeast cells are typically much larger than bacterial cells and can be distinguished from bacteria microscopically by their larger size. A single cell of Saccharomyces cerevisiae is about 6 μm in diameter.

On the other hand, red blood cells have a diameter of 6 - 8 μm.
