This question lacks options, however, it can be answered based on general understanding. The answer is;

It leads to an increase or rise in the global atmospheric temperature, called GLOBAL WARMING.

Explanation:

Carbon dioxide (CO2) is an atmospheric substance (gas) that has the ability to trap and emit heat. This property makes it a renowned green house gas. An increase in the amount of CO2 in the atmosphere will lead to a rise in the Earth's global temperature.

This process whereby the atmospheric temperature of the Earth increases is called GLOBAL WARMING, and it affects the climate of the world and carbon cycle of the Earth.

Solar power is referred to as solar radiation. The amount of solar energy that reaches the earth is referred to as insolation. The radiation that the planet emits is known as terrestrial radiation.

A tiny amount of radiation from the Earth's surface and the warmed upper atmosphere both radiate into space. The majority of the longwave radiation produced warms the lower atmosphere, which then warms the surface of our planet.

Therefore, long wave terrestrial radiation is primarily responsible for warming the atmosphere. The majority of the energy that reaches the earth's surface is in short wavelengths. Incoming solar radiation, often known as insolation, is the name for the energy that the earth receives from the sun.

The example that includes only chemical changes that occur in the digestive process is the reaction of saliva, stomach acid, bile, and pancreatic juices with food. Option D.

Chemical changes refer to changes to the chemical properties of substances. In biological reactions, these substances are referred to as reactants.

Chemical changes are different from physical changes. In physical changes, only the physical properties of substances are altered while their chemical properties remain intact.

When a substance changes chemically, its physical properties most often change along. However, this is not in all cases.

Thus, looking at the examples given, their classification into either physical or chemical changes is as follows:

When saliva, stomach acid, bile, and pancreatic juices react with food, the chemical properties of food change because the enzymes convert different components of food from one form to another as part of the process of digestion.

Considering the probabilities of these outcomes, the chance of having a child with blood type O is 50% if a man with blood type AB marries a woman who is heterozygous for blood type B.

To determine the probability of having a child with blood type O, we need to analyze the possible blood type combinations that can result from the parents' genotypes.

The man has blood type AB, which means he has both A and B antigens on his red blood cells. The woman is heterozygous for blood type B, meaning she carries one B allele and one recessive O allele. The possible genotypes for the man are AB (IAIB) and the possible genotypes for the woman are BB (IBIB) or BO (IBi).

When these two individuals have offspring, their children can inherit any combination of the parents' alleles. The possible combinations are as follows:

AB x BB: All children will have blood type B (IBIB), as both parents only carry the B allele.AB x BO: There is a 50% chance that each child will inherit the O allele from the mother, resulting in blood type O (ii). There is also a 50% chance that each child will inherit the B allele from the mother, resulting in blood type B (IBi).

Explanation:

A higher percentage of compact bone portion typically results in a heavier bone, as compact bone is denser than spongy bone and contains more mineralized tissue.The marrow from a chicken bone is usually soft and gelatinous, with a slightly yellowish-white color.The marrow from a beef bone is typically firmer and more solid than chicken marrow, with a reddish-brown color.I apologize, but there seems to be a question missing from the sequence.The denser marrow was not specified, so I cannot answer this question.The overall density of the bone would be impacted by the density of the marrow, as well as the density of the compact and spongy bone portions.The density of the bone is related to the activities and environment of each animal. For example, birds that fly and need to be lightweight tend to have bones with a higher percentage of air spaces and spongy bone, which reduces weight. Cattle, on the other hand, have denser bones to support their larger bodies and movements on land.

A neurotransmitter from a presynaptic neuron causes an inhibitory postsynaptic potentials (IPSPs), in the postysynaptic neuron. The following event will occur first : Potassium ligand-gated channels open.

Inhibitory postsynaptic potentials or IPSPs, on the other hand, are triggered by the opening of chloride channels. The equilibrium potential of chloride is -65 mV. Thus, if a neuron is resting at −60 mV, chloride channels will flow into the cell due to the electrochemical gradient when the chloride channels open.

As an inhibitory neurotransmitter, GABA normally causes hyperpolarization of postsynaptic neurons, producing inhibitory postsynaptic potentials (IPSPs), whereas glutamate causes depolarization of postsynaptic neurons, producing excitatory postsynaptic potentials ( EPSP).

IPSPs are generated when inhibitory presynaptic cells attach to dendrites and initiate action potentials. Presynaptic inhibitory neurons are involved in the release of specific neurotransmitters.

Answer:

The answer is B. The cell divides once to form two identical cells.

Explanation:

The law of conservation matter is conserved in the cycle of Photosynthesis and cellular respiration.

This is because matter like carbon dioxide and water go into the plant and, with the help of energy, the plant creates a new form of matter -- Sugar, or glucose, and releases the oxygen into the atmosphere that is Formed from the carbon dioxide.

Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other.

Explanation:

The law of superposition states that fossils found in the uppermost layers, i.e., layer A, are more recent than those found in the other layers, so option A is correct for the youngest fossil.

When the environment changes due to climatic changes, animals or plants remain under the rocks, leaving their imprints or hard parts of their bodies, which are later studied to learn about ancestors. The fossils that are present in the lowermost rock layers are the oldest, while the uppermost layer is the youngest as it is newly formed.

As a result, the law of superposition states that fossils found in the uppermost layers, i.e., layer A, are more recent than those found in the other layers, so option A is correct for the youngest fossil.

Answer: photosynthesis

Explanation:

If all fours plants were watered daily but placed in a closet receiving no sunlight then photosynthesis would not occur.

Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time. The biological systems on the planet largely receive energy from this method.

Without light, plants will lose their color and deteriorate. Due to inadequate photosynthesis, the shoots exposed to "limited/no" sunlight were yellow/white in hue. The sprouts struggled to make enough chlorophyll to give them a green color since photosynthesis was hindered by the lack of sunlight.

Thus, if all fours plants were watered daily but placed in a closet receiving no sunlight then photosynthesis would not occur.

Environmental Factors Interact with Genes

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

Answer:

The rock must be eroded into sediment

Explanation:

In order to form sedimentary rock, the accumulated sediment must become compacted and cemented together.

For any type of rock to become sedimentary rock, the rocks must first be eroded into sediment. Thus, the correct option is C.

Sedimentary rocks are the types of rock which are formed by the accumulation or deposition of different minerals or organic particles at the Earth's surface, followed by cementation. Sedimentation include all the processes that cause these particles to settle in place.

Clastic sedimentary rocks form from the accumulation and lithification of the mechanical weathering debris on the Earth's surface. Examples of sedimentary rocks include breccia, conglomerate, sandstone, siltstone, and shale.

Therefore, the correct option is C.
