Answer:

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division (mitosis/meiosis). There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis. Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).

Explanation:

False a temperature significantly higher than the ideal temperature for a specific enzyme is likely to affect the enzyme's activity & reaction rate due to differences in the active site's size and shape.

A component known as an enzyme works as a catalysts in living things to speed up chemical reactions without undergoing any changes. Enzymes manage the majority of the chemical reactions that make up the biological activities that take place inside of all living things.

Reduced activation energy, or the quantity of energy required for a reaction to start, is a crucial function of enzymes. In order to facilitate the bond-forming and bond-breaking processes in chemical reactions, reactant molecules must bind to enzymes in order for them to hold the reactant molecules.

The Astronomers determine estimates for the age of the universe from (1), (2), (3), and (5).

The entirety of time, space, and everything in them, including all known types of matter and energy, make up the universe. Everything that exists is included in it, from the tiniest subatomic particles to the largest known formations, such galaxies and superclusters.

Astronomers have arrived at their estimates for the universe's age in the following ways:

(1) Hubble expansion rate: Using this technique, the redshifts of far-off galaxies are used to calculate the pace at which the universe is expanding. By projecting backwards from the universe's present expansion rate, the age of the universe can be determined.

(2) The amount of the radioactive element uranium-238 in old stars may be measured, and its decay rate can be used to determine the age of the stars and, by extension, the age of the universe.

(3) Radioactive dating of old Earth rocks: This technique entails figuring out the ages of the planet's oldest rocks using radioactive dating methods, which offers a more conservative estimate of the universe's age.

(5) The age of the oldest globular clusters in the Milky Way galaxy can be used to calculate the age of the universe using this approach, which is number five.

Thus, the appropriate choices are (1), (2), (3), and (5). Although it is employed in other cosmological investigations, the amount of dark energy is not used to directly calculate the age of the universe.

The steps of mitosis in the correct order as shown in the attached image is:

Mitosis refers to the process of cell division in which two daughter cells are produced from a single parent cell.

During mitosis, the cell and its contents are divided into two. The chromosomes are also duplicated to ensure that the number of chromosomes in each daughter cell is diploid.

The steps of mitosis are as follows:

Interphase:  this stage is composed of the first cell growth phase, G1, an S phase involving DNA synthesis, and the second cell growth phase, G2.

Prophase: here, centrioles move apart, chromatin is condensed and chromosomes become visible.

Metaphase: chromosomes separate to the equators.

Anaphase: sister chromatids separate and move to the opposite poles of the cell.

Telophase:  sister chromatids become new chromosomes, centriole pairs form outside each of the nuclei.

Cytokinesis occurs and then the genetic material of the new daughter cells is no longer condensed.

Primary succession and secondary succession are two different processes of ecological succession that occur after a disturbance in an ecosystem.

Primary succession is the process by which a new ecosystem is formed on barren land where no soil or organisms exist, such as after a volcanic eruption or glacial retreat.

The process begins with the colonization of bare rock or sand by pioneer species like lichens and mosses. Over time, these organisms break down the rock or sand, creating soil that can support the growth of larger plants like grasses and shrubs. Eventually, trees and other complex organisms take root, creating a mature ecosystem.

Secondary succession, on the other hand, occurs when a disturbance, such as a wildfire or human activity, destroys an existing ecosystem but leaves behind soil and some organisms.

The process begins with the growth of pioneer species that can quickly colonize the area, such as weeds and grasses. As the ecosystem recovers, more complex organisms move in, and the ecosystem slowly returns to its previous state.

In summary, primary succession occurs on bare land without soil or organisms, while secondary succession occurs on land that has been disturbed but still contains some soil and organisms. The processes of succession are essential for the renewal and recovery of ecosystems after a disturbance.

C. The movement of water from the central vacuoles of cells into the solution

The most direct explanation for changes in cells is the flow of water from the core vacuoles of the cells into the solution. Water enters and exits cells via osmosis. Thus, option C  is correct.

Aging causes alterations in all cells. They enlarge and lose their capacity for division and multiplication. In addition to other modifications, the cell's inside now contains more colors and fatty compounds (lipids).

To increase tissue, cells regularly proliferate by themselves. This may occur while an organism is developing or when it sustains an injury and needs to heal itself.

Therefore, the movement of water from the central vacuoles of the cells into the solution most directly explain changes in cells.

The answer is C.

Explanation:

Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A

Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.

One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.

EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.

Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.

While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

Answer:

It causes the release of some hormones from the pituitary,,,,

The half-life of phosphorus-32 (P-32) is  14.8 days.

N(t) = N₀ * (1/2)^(t / T₁/₂)

N(t) is the amount of the substance remaining at time t

N₀ is the initial amount of the substance

t is the elapsed time

T₁/₂ is the half-life of the substance

Initial amount (N₀) = 2 g

Final amount (N(t)) = 0.25 g

Elapsed time (t) = 42 days

We can rearrange the formula to solve for the half-life (T₁/₂):

(1/2)^(t / T₁/₂) = N(t) / N₀

t / T₁/₂ = log₁/₂(N(t) / N₀)

t / T₁/₂ = log(N(t) / N₀) / log(1/2)

t / T₁/₂ = log(0.25 g / 2 g) / log(1/2)

t / T₁/₂ = log(0.125) / log(1/2)

t / T₁/₂ = -log(8) / log(2)

T₁/₂ = -t / log(8) * log(2)

T₁/₂ = -42 days / log(8) * log(2)

T₁/₂ =  14.8 days
