DNA Ligase is responsible for: A. adding the new bases. B. keeping the strands separated during replication. C. linking the short sections of the lagging side. D. unwinding and separating the DNA strands.

Answers

☯️ The DNA ligase is responsible for :

Linking the short sections of the lagging side.

Explanation:-

The ligase is a enzyme responsible for the linking or joining of short sections or strands. It connects the strands by forming a bond between the phosphate group of one DNA strand with deoxyribose group of other.

It is also used in Okazaki fragments connection which are formed in the lagging side during DNA replication. So, We can say that DNA ligase is a specific enzyme which helps in the linking and connecting the DNA strands or fragments by the formation of phospodiester bond[tex].[/tex]

A blow to the cheek is most likely to break which superficial bone or bone part? (a) superciliary arches, (b) mastoid process, (c) zygomatic arch, (d) ramus of the mandible

Answers

Answer:

The correct answer is option c, that is, zygomatic arch.

Explanation:

In anatomy, a section of the skull produced by the temporal bone’s zygomatic process and the zygomatic bone’s temporal process is known as the cheekbone or the zygomatic arch. Temporal bone refers to a bone, which protrudes frontward from the skull side, that is, over the opening of the ear, while the zygomatic bone is the lateral to the cheekbone.  

When a blow takes place to the cheek then the superficial bone or the part of the bone that breaks most likely is the zygomatic arch.

why are the leaves of desert plants reduced into thorns​

Answers

The leaves of the desert plants are reduced to spines/thorns to help to prevent the loss of water by transpiration. Since in deserts, there is a scarcity of water, if the plants lose more water, they will not survive. Hence to prevent this such adaptations have been developed.

The heat of the desert is hash so they are thorns so the predictors don't drink their water

Water molecules are polar. Explain the distribution of charge in a molecule of water.

Answers

Answer:

Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atom.

Water molecules are polar because it determines the bent shape of the molecule in which the partial negatively charged atoms are covalently bounded to the partial positively charged hydrogen atoms.

What are the other characteristics of water molecules?

The other characteristics of water molecules are as follows:

It acts as a universal solvent.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.

The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.

This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.

Therefore, it is well described above.

Which of the following was Theodor Schwann's contribution to our understanding of cells

A. Cells are the basic units of life.

B. All plants are made of cells.

C. All animals are made of cells.

D. All cells are produced from existing cells.​

Answers

Answer:

C

Explanation:

In 1839, Theodore Swhwann, a German Zoologist examined bits of animals under a microscope and observed that animals were composed of cells.

What are the key features of life? Select all that apply. Organisms acquire energy and nutrients through consumption of other organisms. Organisms sense and respond to changes in their environment. Organisms are composed of one or more cells. Life is sustained by inputs of energy and nutrients. Genetic information in the form of DNA is passed to offspring.

Answers

Answer:

Organisms sense and respond to changes in their environment.

Organisms are composed of one or more cells.

Life is sustained by inputs of energy and nutrients.

Genetic information in the form of DNA is passed to offspring.

Explanation:

Not all organisms acquire energy by consuming other organisms. Most green plants, for example, are able to produce their own food by photosynthesis.

Organisms are able to sense and respond to changes in their environment. Without these, survival would be limited. Plants are able to sense and respond to light, water, gravity, etc. while animals are able to sense dangers and run away from them.

According to the cell theory, all living organisms are made up of cells. The simplest organism must contain, at least, a cell, while more complex organisms are made up of several cells.

Life is generally sustained by the input of energy from the sun and that of nutrients from reservoirs such as soil. Plants are able to manufacture their foods by using the energy from the sun and other animals either depend directly or indirectly on plants for their own energy. Important nutrients are cycled from their reservoirs to living organisms and vice versa.

Genetic information in the form of DNA is passed from one generation to another during reproduction. Reproduction is an important attribute of living organisms and it remains the only way life is sustained on the planet.

Atoms can be seen with the naked eye. C. All atoms are the same. D. Atoms make up every substance around you.

Answers

Answer:

Atoms make up every substance around you.

You cannot see single atoms without a special microscope. But every substance around you is made of atoms.

Explanation:

Atoms make up every substance around you is the true statement. Therefore, option (D) is correct.

What are atoms?

An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids.

Moreover, at the most basic level, all organisms are made of a combination of elements. They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs.

Every day, our bodies take in new atoms from the air we breathe, the food we eat, and the liquids we drink. These atoms are incorporated into our cells and fuel the chemical processes that keep us alive.

Our solar system is made up of the Sun and the astronomical bodies that orbit it. But you may be surprised to learn
that all the planets and nearly every asteroid in the solar system orbit the Sun in the same plane and in the same
direction. They all move counterclockwise, if viewed from above Earth's North Pole. What do you think caused this
phenomenon?

Answers

Answer:

Hey there!

This can be explained using the conservation of angular momentum, which the planets get attracted to the sun because of its large size, and massive gravitational pull.

Let me know if this helps, or if you need a further explanation :)

The cause of the phenomenon leading to the clockwise movement of the planets in the same direction would be:

- 'Conservation of Angular Momentum'

Solar System

The various planets and asteroids present in the solar system function in the same path and direction.

The key reason behind this is the 'angular momentum' which leads them to rotate in a linear manner.

The conservation of this constant angular momentum allows these bodies to conserve the very same path along with direction due to their size and gravitational energy.
