Answer:

Hydrogen ions (H+) are essential for the production of ATP because it provides energy in order for ADP to be converted to ATP.

Explanation:

Ion- In Science, "ion" is defined as an atom or a molecule that has a net electric charge. A net electric charge means that the total number of protons (subatomic particles with positive electric charge) is equal to the total number of electrons (subatomic particles with negative electric charge).

Hydrogen ion- This is an atom of a Hydrogen element.

ATP- This is also known as adenosine triphosphate. This is a molecule with high energy or a molecule that carries energy within the cells.

ADP- This is also known as adenosine diphosphate. This is an organic compound that consists of adenosine (a common medication used to treat tachycardia or a fast heartbeat) and two phosphate groups.

ATP is importantly converted to ADP in order to release a free energy that can make a cell condition favorable. In order to do so, the process of oxidative phosphorylation happens. Here, the hydrogen ions pass through the inner mitochondrial membrane (IMM) through ATP Synthase (an enzyme or a membrane protein). The protons then follows through. As it happens, the ADP is converted into ATP.

Explanation: Loam soil is made up of silt, sand and clay. It is richer in humus than the sandy soil. It is suitable for growing most varieties of crops as it retains water and has humus for plant growth.

The segregation of homologous chromosomes occurs during anaphase I of meiosis I, with each daughter cell receiving one chromosome from each homologous pair, forming haploid cells.

The segregation of homologous chromosomes occurs during meiosis, specifically in anaphase I of meiosis I. During this stage, the previously aligned chromosomes at the metaphase plate are separated and pulled to opposite poles of the cell. This process ensures that each daughter cell receives one chromosome from each pair of homologous chromosomes, leading to the production of haploid cells. These haploid cells contain a single set of chromosomes, which contributes to genetic diversity when they combine during fertilization. Moreover, the independent assortment of chromosomes during meiosis I contributes to the unique combination of genetic material in the resulting gametes.

During meiosis, the segregation of homologous chromosomes occurs in two stages. The first stage is during anaphase I, when homologous chromosomes, which are paired up as bivalents, separate and move to opposite ends of the cell. The second stage is during metaphase II, when the sister chromatids of each chromosome, resulting from the earlier separation of homologous chromosomes, separate and move to opposite poles of the cell.

Answer:

Freshwater is a hypotonic solution, which causes the plant cells to swell because of turgor pressure

Explanation:

Fresh water is hypotonic to plant cells thus the plant cells absorbs water osmotically, the cell's vacuole enlarges, exerts an outward pressure on the cell wall called turgor pressure and becomes turgid, which keeps the plants upright.

The pressure increases as more water is taken into the vacuole which pushes the cytoplasm against the cell wall until the cell wall cannot stretch anymore. When  the cell wall is being stretched outside it develops a resistant pressure to stretching that is equal and opposite to turgor pressure called wall pressure.

Answer:

A major change over long periods of time is best described as macroevolution.

Explanation:

Macroevolution would be referring to evolution on a larger scale where populations speciate etc. A, B and C are various forms of speciation and microevolution would be referring to smaller changes in evolutionary patterns e.g. in adaptive or physical traits which may not be deemed 'significant' enough to be considered a speciation event.

I think it is: acetylcholine (neurotransmitter) - motor neuron - contract

second question: diffusion because of opening of ca2+ channels

Acetylcholine is used by the somatic nervous system at the neuromuscular junctions, where it causes the firing of motor neurons and influences voluntary movements. Thus, option D is correct.

If calcium ions are available, they attach to troponin and modify its shape, allowing tropomyosin to migrate away from the myosin-binding sites on actin.

Tropomyosin generally blocks, however when there is a high calcium ion concentration, the calcium ions attach to troponin and modify the troponin's confirmation, which causes the tropomyosin to shift out of the way.

A burst of intracellular calcium ions that bind to troponin on the actin-containing thin filaments of cardiac muscle cells causes each heartbeat.

Therefore, diffusion is the process Calcium Ions move by which mechanism into the cell and bind with tropomyosin and troponin.

Explanation:

The electron transport chain in photosynthesis involves the excitation of electrons from chlorophyll and the splitting of water molecules, while in cellular respiration, electrons come from NADH and FADH2. Both processes generate ATP through an electron transport chain and oxidative phosphorylation.

The electron transport chain in photosynthesis and cellular respiration have some similarities and differences. In photosynthesis, electrons from chlorophyll molecules are excited by light energy and passed through the electron transport chain in the thylakoid membrane of the chloroplasts. The high-energy electrons come from the splitting of water molecules, and the energy is used to produce ATP and NADPH.

In cellular respiration, electrons from NADH and FADH2, generated in earlier steps of respiration, are passed through the electron transport chain in the inner mitochondrial membrane. The ultimate electron acceptor is oxygen in aerobic respiration or other inorganic molecules in anaerobic respiration. The energy from the electrons is used to generate an electrochemical gradient and produce ATP through oxidative phosphorylation.

In summary, photosynthesis uses light energy to excite electrons from chlorophyll and water molecules, while respiration uses electrons from NADH and FADH2. Both processes involve an electron transport chain to generate an electrochemical gradient and produce ATP.

An increased population of smaller fish could lead to decreased populations of primary consumers and producers, and may contribute to biological magnification if toxic substances are present.

An increased population of smaller fish in an aquatic ecosystem could have several consequences. One possible effect is decreased primary consumers as the smaller fish may consume more aquatic insects and water fleas, thus reducing their populations. Another effect may be decreased producers, because with more small fish eating algae, the producer population may suffer, potentially affecting the whole food web due to lack of food for primary consumers.

Additionally, if persistent toxic substances are present in the ecosystem, biological magnification could occur, where these toxins accumulate in higher concentrations as they move up the trophic levels from algae to small fish to larger predators such as large fish or turtles.

An increased population of smaller fish in an aquatic ecosystem can lead to two possible consequences: decreased producers and decreased primary consumers.

1. Decreased producers: The increased population of smaller fish can result in higher predation on primary consumers such as aquatic insects and water fleas. This can lead to a decrease in the number of primary consumers, which in turn reduces the consumption of algae, the producers in the food web. As a result, there may be a decrease in the overall population of algae in the ecosystem.

2. Decreased primary consumers: Another consequence of an increased population of smaller fish is a potential decline in the population of primary consumers. This is because the smaller fish may consume more primary consumers, causing a decrease in their numbers.

It is important to note that these consequences are based on the assumption that smaller fish are predators of primary consumers in the food web. However, the specific dynamics of an ecosystem can vary, so these consequences may not always apply.

They have a zero percent chance of developing the disease

All the offspring will be carriers of the mutated gene but none of them will show any phenotype associated with the recessive allele. This is because they all will have the dominant allele that will mask the effects of the recessive allele of the gene.

Explanation:

Autosomal means that the allele is not on the X or Y sex chromosomes hence it is not a sex-linked gene. Male and female offspring have equal chances of acquiring the allele of the genes.  

Let us assume that the dominant allele is coded by B while that of the recessive is coded by b. The attached Punnet square will show the Mendelian  inheritance based on the information from the question.

Therefore, all the offspring will be carriers of the mutated gene but none of them will show any characteristics of the disorder (phenotype) associated with the recessive allele. This is because they will all have the dominant allele that will mask the effects of the recessive allele of the gene.

Answer:

active immunity

Explanation:

Active immunity is the form of acquired immunity in which the body produces its own antibodies against infections. When infectected by a bacterial infection that had happened before, one will not become seriously ill. This is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens.

Answer:

Biotic factors can be described as the living components of a system. Abiotic factors can be described as the non- living components of an ecosystem. The abiotic and biotic components of an ecosystem are linked to each other by the flow of energy.

Energy usually enters an ecosystem through the abiotic factor, i.e Sun in the form of heat. This energy is essential so that the biotic component, plants, can make their own food. Some of the heat energy is dissipated back into the atmosphere in the form of heat. Rest, the energy is directed to herbivores, carnivores and decomposers. All these organisms also dissipate some of the heat energy back into the atmosphere.

Answer:

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2)

Explanation:

Photosynthesis is the process carried out by plants so that there is the production of energy necessary for them to stay alive. Unlike animals, plants produce their own food.

In short, it is the production of food by the plant itself. In order for this process to happen, the plant removes carbon dioxide from the air and also uses energy from the sun. The products resulting from this process are the glucose that will promote the carbon absorption of the plant, and oxygen that will be released into the atmosphere.

FACTORS THAT CAUSE GENETIC VARIATIONS

Answer:

Genetic variation is caused by:

mutation

random mating between organisms

random fertilization

crossing over (or recombination) between chromatids of homologous chromosomes during meiosis

Explanation:

The variations in human skin color result from genetic adaptations to different environments and UV radiation exposure. They varies due to adaptations to environmental conditions and UV radiation exposure.

Skin color is determined by the amount of melanin in the skin which is controlled by multiple genes. This variation in melanin production is an evolutionary response to different levels of UV radiation in various regions of the world.

In areas with intense sunlight such as near the equator, people tend to have darker skin with more melanin to protect against harmful UV rays. In regions with less sunlight, individuals have lighter skin with less melanin to enable the production of vitamin D which is essential in low-light environments.

Answer:

C. Anaerobic

Explanation:

To produce energy for our muscles and organs, our body needs to breathe in oxygen. It is known as aerobic respiration, takes place in the mitochondria of our cells. But there are cases when our bodies cannot get enough oxygen, like when we're working out very hard or holding our breath.

Our cells then switch to anaerobic respiration. Like a backup plan for producing energy without oxygen. In our cells, anaerobic respiration takes place in the cytoplasm.

There's a catch, though! The amount of energy produced by anaerobic respiration is less than that of aerobic respiration. Also, it produces lactic acid, a waste product that can make our muscles feel fatigued and sore and, if it builds up, can cause painful cramps.

So, while anaerobic respiration is helpful in a pinch, it's not as efficient as aerobic respiration in the long run.

The Rainforest

There are more than 10 million species of plants and animals on earth, and more than half of them reside in our rainforests.

Most species in the world are found in tropical rainforests due to their high biodiversity, stable temperatures, and plentiful rainfall.

Most of the species in the world are located in tropical rainforests. These environments are characterized by high biodiversity due to stable temperatures, high rainfall, and a multitude of available niches. In contrast, biomes such as deserts and the tundra have more extreme conditions and tend to have lower biodiversity. Deserts, for instance, have very little rainfall and poorer soil conditions which limit plant growth and subsequently the diversity of animal species. Similarly, the Arctic tundra experiences short growing seasons and is known for extreme cold, which also limits the diversity of species. Conservationists often focus on tropical rainforests when designing ecological preserves to protect the rich diversity of species found there.
