Answer:

Water as a constructive force: It is involved in the deposition of sediments. It transports rock fragments, soil, and other debris at a particular area. This process eventually causes them to accumulate and form land features. Water as a destructive force: It is involved in weathering and erosion.

Explanation:

(pls mark brainliest if u can)

:)

Water can be both a destructive and a constructive force.

• The forces, which form or create an existing landform are known as the constructive forces. While the force, which tears or lowers down the surface features of the Earth are known as the destructive forces.

• Water can be considered as the constructive force as it carries sediment down the river and with the river becoming shallow, the deposition of the sediments takes place giving rise to landforms called deltas.

• On the other hand, water can also be considered as a destructive force as it takes part in processes like erosion and weathering. It breaks down and wears away the rocks and land masses.

Thus, water can be both destructive and constructive.

Answer:

C. Is travelling on a curve in the road.

Explanation:  the two vehicles behind the truck is moving at a constant speed because there is no change in velocity. The truck is changing directions AND speed (Acceleration/Velocity).

The  pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound).

Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).

Therefore, The  pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.

Answer:

Sperm have a well-protected head and a motor to help them travel.

Explanation:

Gametes are sexual cells. Organisms make use of gametes to sexually reproduce themselves. Male organisms produce gametes called SPERM while feale organisms produce gametes called EGG. Although both of these gametes function to sexually reproduce the organism that produces them, they have different morphological characteristics that supports their physiological function.

- The sperm cell is made up of two major parts namely: the head and the tail. The head of the sperm cell contains the nucleus, which houses the genetic material of the cell i.e. DNA. For this reason, the head is well protected. Also, the sperm contains a tail region, which is actually a flagellum that enables it to be motile i.e swim through the female reproductive part. The flagellum contains a structure called AXONEME, which is referred to as the MOTOR of the sperm cell.

Yeast cell structure

Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.

Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.

Explanation:

Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.

Answer:

4

Explanation:

The correct answer would be hydrotropism and thigmotropism.

Hydrotropism is defined as the movement of a plant or its organs to or away from moisture. The deep root growth of plants is a way of seeking or growing towards moisture that is present deep in the soil. Hence, the root is said to exhibit positive hydrotropism.

Thigmotropism, on the other hand, is the growth or movement of plants or their organs to or away from touches. In this case, the tendrils of the plant that wraps around objects they come in contact with are showing positive thigmotropism.

The correct option is, therefore, option 4.

I think the answer is clouds.

Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Water vapor in the atmosphere is visible as clouds and fog.

answer:

Precipitation is most abundant where air rises, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.

Plant parts are flattened and at least some of the original plant material remains. Leaves are often preserved as compressions.

There are two cells in accordance to research.

Answer:

The model is inaccurate because the base pairs are incorrect.

Explanation:

The model of DNA that the student made was:

G-G

A-A

T-T

C-C

G-G

A-A

T-T

C-C

The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.

The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

the more carbon dioxide in the blood the more acidic it will be. so when it is removed the acidity will decrease.

so the pH increases

When the body removes carbon dioxide, the PH of blood​ increases

The body control the blood's acid-base balance through different ways. The organs used for this control is lung, kidney and buffer systems.

The lung can control blood pH through the release of carbon dioxide. Carbon dioxide acidic and its accumulation in the body leads to an increase in PH.

When the blood PH is too low (i.e. acidic), the body increases breathing so as to expel(remove) more carbon dioxide thereby increasing the PH of the blood.

A. intraspecific !!

Wolves from the same pack are all feeding on the same deer. What type of species. In this, the type of the species is intraspecific competition.

Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce.

Interspecific competition may occur when individuals of two separate species share a limiting resource in the same area. If the resource cannot support both populations, then lowered fecundity, growth, or survival may result in at least one species.

Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area.

The distance from the earth to moon changed is most likely caused the difference in the apparent size of the Moon in photographs A and B.

One of the solar system's most recognizable objects is the Moon. Due of its closeness to Earth, it has enormous cultural value and is crucial to the regulation of the planet's tides.

The Moon has essentially little atmosphere, thus it cannot retain heat or act as a surface insulator.

The Moon's surface reaches 127°C in full sunlight, which is far over the boiling point of water. High temperatures last for 13 and a half days, followed by 13 and a half days of darkness.

Answer:

Please find a detailed explanation of the process below

Explanation:

Transcription is the first stage of gene expression in living organisms in which a DNA sequence is used to synthesize a mRNA molecule. This process, which occurs in the NUCLEUS of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA POLYMERASE.

- In the initial stage called INITIATION, RNA polymerase binds to the promoter of GENE and starts to unwind the double strand of the DNA sequence.

- The RNA polymerase, then, begins to add complementary NUCLEOTIDE bases following the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will pair with Thymine (Uracil in RNA) while Guanine will pair with Cytosine i.e. T-A, A-U, G-C etc. This stage is called ELONGATION.

- The last stage called TERMINATION involves the stopping of the process because the RNA polymerase has encountered a termination signal.
