Explanation:

Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species. ... Genetic diversity serves as a way for populations to adapt to changing environments.

The need to increase efficiency and productivity while preserving natural resources, especially water and soil, is great. ... Advertisement. In light of these realities, growers are under pressure to produce more, pollute less, fulfill consumer preferences, and make a living.

Answer: The assertion is true and the reason is the correct explanation of the assertion

Explanation: This statement is true because the plasma membrane is selectively permeable, meaning that it allows some substances to pass through it while preventing others from crossing it. Gases like oxygen and carbon dioxide are small molecules that can easily diffuse through the membrane due to their size and lack of charge. Additionally, the plasma membrane has channels and pumps that specifically facilitate the movement of gases across the membrane. Therefore, metabolic gases can freely diffuse across the plasma membrane due to the permeability of the membrane.

Explanation:

Random mutations in genes can potentially lead to advantageous characteristics. For example, a mutation in the genetic coding of a bacterium could lead to that bacteria becoming resistant to antibiotics. Mutations change the overall coding of a gene, and are normally harmless. Mutations are changes in the coding of DNA, they can lead to alterations in the polypeptide chain and so can lead to non-functional proteins.

Sexual reproduction with a short reproductive cycle would probably increase a species' chances of survival as the climate changes. Therefore, option (1) is correct.

The fusing of a haploid female gamete (egg cell) with a haploid male gamete (sperm cell) is known as sexual reproduction. Reproduction requires either one parent (asexual reproduction) or two parents (sexual reproduction).

Asexual reproduction is typically undesirable because the environment is always changing. Sexual reproduction is generally preferred. Asexual reproduction results in organisms that are exact copies of their parents. The process of sexual reproduction can result in the development of new genetic combinations. The variety of phenotypic qualities is also increased by the genetic diversity of organisms.

During meiosis, independent assortment and crossing-over take place, which causes variation. This variation provides organisms the ability to adapt to a changing environment so that they will live and reproduce in the new habitat. In doing so, sexual reproduction would be able to adjust to new environmental challenges. And a shorter reproductive cycle allows it to produce more offspring.

Incomplete Dominance

Explanation:

Several inheritance patterns exist which do not follow Mendel's inheritance pattern called NON-MENDELIAN INHERITANCE. Some of them are incomplete dominance, co-dominance etc.

Incomplete dominance is a situation whereby two alleles of a gene are neither dominant nor recessive over one another, hence, they combine in an heterozygous state to form an intermediate third phenotype that is different from both parent's phenotypes.

This is the case in this otters that have brown and white phenotypes (colour). However, they combine to make a new 3rd phenotype.

The majority of ATP synthesis takes place within the mitochondrial matrix during cellular respiration, with each molecule of glucose oxidized creating around 32 A T P molecules.

ATP produced in mitochondria serves as the main energy source for vital biological functions such muscle contraction, nerve impulse transmission, and protein synthesis. The majority of the ATP produced during cellular respiration is created in the mitochondrial matrix, where each glucose molecule that is oxidised yields roughly 32 molecules of ATP.

Gradients are produced as a result of protons being pumped out of the matrix as electrons move down the chain and release energy in the process.

Protons flow back into the matrix and are converted into ATP by an enzyme called ATP synthase.

The inner mitochondrial membrane contains ETS.

The majority of the ATP in cells is produced by the enzyme ATP synthase, which does this by converting ADP and phosphate to ATP. ATP synthase is found in the membrane of mitochondria, which are cellular organelles; in plant cells.

The statements that are true about the distribution of sap throughout a plant are:

a) The driving force for sugar movement is transpiration.

b) The mechanism that explains the movement of sugars throughout a plant is called the pressure-flow hypothesis.

c) Companion cells form the conducting tissue for sap.

Transpiration is the process where water is lost from the leaves of the plant and the resulting negative pressure in the leaves pulls water from the roots.

The pressure-flow hypothesis describes how the pressure difference in the leaves and roots is used to drive the movement of sugars through the plant.

Companion cells are specialized cells found in phloem tissue that help to support the sieve tube cells which are responsible for the actual transport of sap.

Phloem sap is a complex mixture of sugars and other substances and not only glucose.

Answer:

high survival rates of offspring and the cost of parental care

Explanation:

Animals must optimize the energy invested in growing, surviving, reproducing, and leaving fertile offspring. They must ensure the perpetuity of the species. The best manner of doing it is by reaching sexual maturity, mating, and leaving progeny that also reaches their fertile age. So sometimes, they need to "decide" or "choose" where to invest more energy.

Those that "decide" to take care of their offspring invest too much energy in doing it. Parents must feed them, an activity that requires most of their energy to produce food or look for it. They must protect their progeny from potential opportunistic predators, so they need to be near the whole time. They need to teach behaviors and habits. And so many other things that require energy investment.

So, where do parents take all this energy from? The energy that is usually destined for survival and mating activities, is now destined for parenting. Often, parents can not feed properly because they can not leave their offspring alone. They face predators putting themselves in danger of being hurt. They can not mate even if they are in the reproductive season.

This is the Cost-benefits energetic trade-off.

Which is the benefit? To ensure the progeny survival, to make them reach their sexual maturity, and to reproduce too. They do it to ensure the perpetuity of the species.

So these species "choose" to have reduced offspring and to take care of them. Many other species "choose" to have many descendants and to avoid parental care. They invest their energy in surviving and reproducing.

Answer:

It can't be applied to fossils

Explanation:

It's because fossils aren't living organisms.

A researcher discovers a mysterious unknown multicellular eukaryotic organism. She would be confident that it is an animal if she observed that it has specialized organs, such as eyes, ears, or a heart, or if it moved in response to its environment.

Animals are a distinct group of multicellular eukaryotes, and they are characterized by the presence of specialized organs that aid in the collection of energy and nutrients, as well as providing a means for locomotion. These organs can be as simple as a single cell like the cilium on a paramecium, or as complex as the human brain. Additionally, animals usually respond to their environment in some way, such as locomotion or behavioral responses.

The researcher's observation of specialized organs and movement in response to its environment would be a strong indication that the organism is an animal. By looking at the size, shape, and organization of the cells under a microscope, the researcher could further confirm the identity of the organism. For instance, the presence of cilia or flagella would suggest that the organism is a protozoan, while the presence of an organized nervous system could indicate that it is a more complex organism, such as an arthropod or a vertebrate.

The surface area to volume ratio (SA:V) is a mathematical formula used to measure the relative size of a cell. It is the ratio of the surface area of a cell to its volume. Cells need to maintain a high SA:V in order to survive and function properly.

First, a high surface area to volume ratio is needed in order for the cell to take in essential nutrients and expel waste. All cells must take in oxygen, glucose, and other nutrients from the environment in order to survive, and they must also get rid of waste products such as carbon dioxide and other toxins. The surface area of a cell provides an area for the cell to access these materials, and the volume of the cell determines how much material can be moved in and out of the cell. A higher SA:V means that more of the cell's surface area is available to take in materials, and more of the cell's volume is available to expel waste.

Second, a high surface area to volume ratio is also necessary for the cell to carry out its metabolic processes. The metabolic processes of a cell require energy, which comes from the breakdown of glucose and other molecules. A higher SA:V allows for more of the cell's surface area to be used for enzyme-catalyzed reactions, and more of the cell's volume to be used for the storage and transport of molecules to and from the cell.
