Explanation:

gametes are made asexually ad are identical.

Answer:

They speed up chemical reactions and are denatured by high temperatures and high pH.

Explanation:

Enzymes speed up chemical reactions. They have specifc conditions that allow them to work effectively. Temperature and pH affects how enzymes work. The optimum temperature is the temperature at which enzymes will function best. In most instances they are around 37-40°C (in the human body). Temperatures above this will denatured (destroy) the enzymes therefore they cannot do their task. At Temperatures below the optimum temperature the enzymes activity is decreased to the point where they may not be active.

Optimum pH is the pH at which the enzymes works best. These vary based on the type of enzyme. Any pH above the optimum will denatured the enzymes (destroy). pH below the optimum will decrease the ezymes activity to the point where they may not be active

Answer: B

Explanation:

Answer:

Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.

Explanation:

Answer:

As the size of an organism increases, its surface area to volume ratio decreases. ... Large multicellular organisms therefore cannot rely on diffusion alone to supply their cells with substances such as food and oxygen and to remove waste products. Large multicellular organisms require specialised transport systems.

Answer:

Cells need oxygen and glucose.

Without oxygen, electron transport chain cannot take place and the cells cannot get the energy they need (since the cell uses oxygen to break down glucose which os what produces energy). When the cells cannot perform their function, they die.

Answer:

b. ventricles

The right and left ventricles

Answer:

B(ventricles)

Explanation:

So lets go over the heart.

First blood circulates from your body to your heart. This is through blood vessels. These blood vessels are connected to the inferior and superior vena cava that go into the heart.

So, this means that the blood vessels are outside of the heart, not the lower areas.

Then, the blood goes into the right artierium, and down to the right venticle. So, thinking about this, it means that the artieriums are the top chambers.

The word auricles is another word for artiums, which we already know are the top chambers.

The venicles are below this, these must be the bottom chambers.

I attached files of some notes I took on the heart, they show the strucutre of the heart and the workings of the heart and circulatory system.

Hope my answer or notes helps! ;)

Everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

The Big Bang theory is an attempt to explain what happened at the beginning of our universe. Major discoveries in Astronomy and Physics have explained that our universe actually had a beginning. Before that moment there was nothing and after that jump there was something  which is our universe.

According to the widely known theory, our universe sprang into existence as "singularity" which goes back around 13.7 billion years ago. Singularities are basically zones which flout our knowledge of physics. They are assumed to be present at the core of "black holes."

Black holes are regions of enormous gravitational pressure. The pressure is assumed to be so extreme that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of interminable density are called "singularities."

Thus, everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

Weak sustainability is a concept inside environmental economics that states that 'human capital' can substitute 'herbal capital'. It is primarily based totally upon the paintings of Nobel Laureate Robert Solow, and John Hartwick.

Biodiversity loss refers back to the decline or disappearance of organic diversity, understood because of the style of residing matters that inhabit the planet, its distinctive ranges of the organic corporation, and their respective genetic variability, in addition to the herbal styles found in ecosystems.

An environment is a geographic region wherein plants, animals, and different organisms, in addition to climate and landscape, paintings collectively shape a bubble of life. Ecosystems incorporate biotic or residing, parts, in addition to abiotic elements, or nonliving parts. Biotic elements consist of plants, animals, and different organisms although related, sustainable improvement and sustainability are distinctive concepts.

Answer:

B) runoff will increase and less water will penetrate the soil to become groundwater.

D) impervious surfaces such as roads and parking lots will divert water flow and it will not reach its endpoint

Explanation:

The runoff will increase and less water will penetrate into the soil to become groundwater if natural vegetation is replaced by impervious surfaces. The natural vegetation helps to lower the speed and intensity by absorbing large amount of water. Due to this absorbing, there is an increase occur in the concentration of groundwater level which increases underground water reserves for the coming generations. These impervious surfaces also act as a barrier that diverts water and prevents the water to reach to its ending point.

B is the correct answer.
