Answer:

D. organ systems

Explanation:

Organs and tissues that perform the same function are called organ systems

Explanation:

Single circulation is less efficient as gill capillaries slow down the blood flow so the body receives blood at a low pressure which decreases the oxygen supply to the cells.

Double circulation is more efficient as blood at higher pressure especially in humans and mammals

In single circulation only venous blood passes through the heart.

In double circulation mixed or oxygenated or venous blood passes through the heart.

Why are ecosystems with grass better for herbivores than ecosystems with trees?

Trees cannot store a lot of energy in the leaves, so grass would be better.

Some herbivores can't climb trees, so grass is convenient. Grass also produces oxygen at a far greater rate than trees do

The endocrine system produces hormones that control various physiological processes such as reproduction, metabolism, etc. Hormones play a very important role in growth, metabolism and other cell functions.

The endocrine system has endocrine glands. Endocrine glands are ductless glands. They release their secretions directly into the bloodstream. Pituitary gland is the master gland in the body.

There are many endocrine glands in the body which are as:

Pituitary gland is the master gland it controls the all the hormone regulation in the body. Adrenal gland is located at the top of the kidney. It releases glucocorticoids. Thyroid gland play very important role in growth and metabolism.

The combination of two or more atomic orbitals results in the same number of hybrid orbitals, each with the same shape and energy, which is the right response.

The process of two complementary single-stranded DNA or RNA molecules joining together to generate a double-stranded molecule is known as hybridization in the field of genomics. Correct base pairing between the two single-stranded molecules controls the bonding. Determine how many lonely pairs are connected to it. Add up these two numbers.

Add up these two numbers.

Your atom is a sp3 if the response is 4.

Your atom is a sp2 if the response is 3.

Your atom is sp if the answer is 2.

To maximize electron stability in their orbitals, hybridization is necessary.

The characteristic that Venus and Earth share are similar size, mass, and density. The correct option is (B).

The second planet from the Sun and the nearest planetary neighbor to Earth is Venus. It is one of the four inner, rocky terrestrial planets and is frequently referred to be Earth's twin due to similarities in size and density.

Venus and Earth are roughly the same sizes, mass, and density. Both have a fairly similar makeup, but Venus' atmosphere, which is made up exclusively of carbon dioxide, is not the same as Earth's. Venus rotates around the sun at the slowest rate.

Venus is frequently referred to as Earth's twin because both planets are comparable in size, surface makeup, and atmosphere, which includes a sophisticated weather system. Venus is just 30% closer to the Sun than Earth, and both planets are roughly the same size and density.

Therefore, the correct option is (B) similar size, mass, and density.

Answer:

cooling the water

Explanation:

hot water has more energy tha cold water

Cooling the water will most effectively slow down the dissolving of a sugar cube in the water. This is basically based on the rate of dissolution property of water. Hence, option B is correct.

Dissolution refers to the process by which the solute dissolves into the solvent and forms a complete solution.

Rate of dissolution refers to the time taken by a solute to dissolve into a solvent. Any solid that has to be dissolved into water depends upon the collisions between the molecules of the water and the particles of the solid substance. So, to increase the frequency of these collisions, more energy is to be transferred to the system to increase the rate of dissolution.

And, while cooling the water, we are lowering the kinetic energy between the molecules of sugar and the water, that means the collisions will occur with less force. Hence, the rate of dissolution will be lowered.

Therefore, the correct option is B where the cooling of the water will decrease the rate of dissolution of the sugar cube in the water.

Other guy wrong, its:

A

Mode of reproduction for Escherichia coli, a prokaryotic organism

B

Can occur in animals through fragmentation

The statements that are true for asexual reproduction are the mode of reproduction for Escherichia coli, a prokaryotic organism, and can occur in animals through fragmentation. The correct options are A and B.

Asexual reproduction is the type of reproduction in which there is no need for two parents. A single parent can generate offspring. They are of various types like budding, and binary fission. It is done in small organisms or primitive organisms.

Escherichia coli is a prokaryotic organism. It is a bacterium that reproduces by asexual reproduction. In bacteria, the cells of bacteria divide themselves and produce new cells called daughter cells.

Fragmentation is a process of reproduction in which there is the fragmentation of a body part that produces a new organism. It can be seen in a starfish.

Thus, the correct options are:

A. Mode of reproduction for Escherichia coli, a prokaryotic organism

B. Can occur in animals through fragmentation.

Answer:Chemical energy transformations take place from the outlet charger to the ringing phone

Explanation:

Based on the information provided;

The wavelength of a wave is the distance between successive crests or troughs in a wave.

A crest in a wave is a point on the wave surface where the maximum upward displacement of the medium occurs.

A trough in a wave, is the point of the maximum downward displacement of the wave.

The distance between crests in the wave is given as 5 meters.

Thus, the wavelength of the wave is 5 meter.

The frequency of a wave is the number of complete cycles completed by the wave in one second.

From the given data, the wave takes 20 second to complete one cycle.

Therefore, frequency of the wave = 1/20

frequency of the wave = 0.05 Hz

The wave velocity or wave speed is the product of the wavelength of a wave and the frequency of the wave.

Wave velocity = 5 * 0.05

Wave velocity = 0.25 m/s
