B. Dendrite - cell body - axon - terminal branches

is correct

Answer:

b

Explanation:

The statement 'the temperature increases with an increase in atmospheric carbon dioxide' describes the relationship between carbon dioxide and temperature.

Global warming is a climate phenomenon by which the temperature is increasing due to the release of greenhouse gases.

These greenhouse gases are mostly generated by human activities (e.g., industrial activities).

It has been shown that an increase in the emission of greenhouse gases is associated with global warming.

Explanation:

Three choices to accurately explain interactions between these two body systems are:

b. The circulatory system transports oxygen to the organs of the digestive system.

c. The digestive system provides glucose to the circulatory system for transport to tissues.

e. The circulatory system transports absorbed nutrients from the small intestine to the cells.

A digestive system is a group of bodily organs that aid in breaking down complex foods into smaller pieces so they can be more easily absorbed by the body. These organs include the mouth, small intestine, gall bladder, and others.

The cardiovascular system is made up of the heart and blood vessels including capillaries, veins, and arteries that pump and distribute blood throughout the body.

Answer: Increased interest in public transportation

Explanation: got it right

Due to public transportation, more vehicles need more petroleum, leading to an increase in petroleum prices, hence option a is correct.

Petroleum prices are likely to have risen as a result of both increased demand and worries about supply interruptions. Global demand for oil has been rising, exceeding any increases in supply and surplus capacity.

One major reason is that developing countries, particularly China and India, have been quickly rising. These economies have grown more industrialized and urbanized, contributing to an increase in global demand for oil.

This is because transportation costs will rise, raising the prices of numerous commodities. This is cost-push inflation, as opposed to inflation produced by increased aggregate demand excess growth.

Therefore increased interest in public transportation, leads to rising petroleum prices, hence option a is correct.

Biotic -- Insects, Weeds, fungi, bacteria, etc

Abiotic -- Sunlight, water, CO2 levels, Salinity, Pressure, etc

Explanation:

Plant development and crop output can be significantly impacted by both biotic (such as weeds, insects, fungi, and bacteria) and abiotic (such as sunshine, temperature, rain, humidity, drought, salinity, air, soil, pollution, magnetic fields, etc.) variables.

Temperature and moisture have a significant impact on the amount of organic matter that is available for use as food and plant production (primary productivity) (net primary productivity).

To support life, development, and reproduction, trees require sufficient amounts of water, heat, light, nutrients, carbon dioxide, oxygen, and other abiotic resources.

Therefore, Biotic and abiotic factors that affect tree growth in Kuwait.

Human embryo have many characters that disappear during their growth. Tail bone is vestigial in humans, they have hair and produce milk indicates that these are mammal.

Mammals are the animals that have some unique feature like giving birth to young once, have mammary gland, having body hair, etc.

The appearance of tail in mammals just like fish, amphibians shows evolution.

Humans have hair and mammary gland which produce milk to nourish the young means they belongs to mammals.

Thus, all these characteristics shows the evidences of evolution.

What is matter?

~ Matter is something which all physical objects are believed to be made of -- it is a material substance that occupies space, possesses mass, and is made up mostly of atoms (basic unit of matter) which consists protons, neutrons, and electrons, that constitutes the observable universe.

~ State of matter is the distinction or the difference in forms of matter we can observe in our daily life. The 5 states of matter thus far are; solid, liquid, gas, plasma, and bose-einstein condensate.

Matters differ in characteristics, appearance and compositions. Written here are the basic differences in 3 most fundamental states of matter.

Solid - a matter which composed of rigid and closely packed particles -- particles move only via vibrations. Has definite shape and definite volume.

Liquid - particles can move back and forth, not too tightly packed -- has definite volume but with no definite shape.

Gas - the particles in gas are relatively far apart compared to solid and liquid, they're moving fast back and forth/side to side, and bouncing nonstop. Gas neither have definite shape nor volume, and is way compressible than solid and liquid.
