4.) two identical nucleotides form

Mitosis is important because it is responsible for the growth of is responsible for human development.

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Answer:

Diorite is a course-grained igneous rock that forms when magma rich in silica cools slowly deep within the Earth's crust.

Or Slow cooling in the upper mantle.

Explanation:

Upper mantle is the condition below would you expect a coarse- grained.

The Earth's upper mantle is a very thick layer of rock that extends from just below the crust (at a depth of 10 km (6.2 mi) beneath the oceans and 35 km (22 mi) beneath the continents) to the top of the lower mantle at a depth of 670 km (420 mi).

At the top boundary with the crust, temperatures range from roughly 500 K (227 °C; 440 °F) to roughly 1,200 K (930 °C; 1,700 °F) at the lower mantle border.

Depending on depth, the upper mantle material that has reached the surface is made up of roughly 55% olivine, 35% pyroxene, and 5–10% calcium oxide and aluminum oxide minerals like plagioclase, spinel, or garnet.

Therefore, Upper mantle is the condition below would you expect a coarse- grained.

4.the sun

5.electrical

Hope this helps fr fr

According to the law of conservation, both energy and matter are conserved in the natural system. Earth as a whole is a closed system, in which energy and matter can move from one sub-system to another.

As energy and matter are transferred between subsystems, different forms of matter and energy interact. For example, during photosynthesis, carbon is transferred from the atmosphere into the biosphere, while radiant energy from the sun is converted into chemical energy.

During this process, the amount of carbon remains constant, but some of the radiant energy is transformed into electrical energy.

The law of conservation may be defined as a physical property that can not change in the course of time within an isolated physical system.

Therefore, the blanks are appropriately filled.

Answer :cellulose

Explanation:

Answer:

intertidal zone is the area of shore between the high tide and low tide lines whereas neritic zone is the area of the ocean from the low tide line out to the continental shelf.

The main difference between the intertidal zone and the neritic zone is the amount of time covered by water.

The intertidal zone is the area of the shoreline that is regularly exposed to air at low tide and submerged at high tide. This area is characterized by its exposure to fluctuations in water level, temperature, and salinity, and is home to a diverse range of organisms that have adapted to these conditions.

The neritic zone, on the other hand, is the shallow ocean water over the continental shelf, extending from the low tide mark to a depth of about 200 meters. Unlike the intertidal zone, the neritic zone is always covered by water and is characterized by relatively stable physical conditions, including a relatively constant temperature and salinity.

While the amount of exposure to sunlight can vary in both the intertidal and neritic zones, the main difference between these two habitats is the amount of time covered by water and the resulting stability of environmental conditions.

Answer:

Eukaryotic cell

Explanation:

The cell of living organisms have been classified as either eukaryotic or prokaryotic depending on whether or not it contains a NUCLEUS. A prokaryotic cell is a cell that does not contain a membrane-bound nucleus to house its genetic material e.g bacteria, archaebacteria etc.

On the contrary, eukaryotic cells possess a membrane-bound nucleus that houses their genetic material e.g fungi, animals, plants etc. Based on the above explanation, an EUKARYOTIC type of cell produces a nucleus.

Explanation:

The pectoral girdle also known as the shoulder girdle forms part of the appendicular skeleton also known as the upper limbs.

It is located at the upper part of the body, connecting each arm to the body.

It consists of the scapula (found on either side of the body) also known as the shoulder blade that joins the collar bone to the humerus.

It also consists of the clavicle ( the only one bone in the body that lies horizontally) located on either side of the body which serves as a system of support for the breastbone and the shoulder blade

Answer:

Below is an attached image of the phylogenetic tree showing the evolutionary history of the four plant  groups in the herbarium.

Answer: The correct answer is -

D. Eukarya has similar evolutionary traits to archaea.

A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.

In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.

Thus, option D) is the right answer.
