d and a

Explanation:

The embryo's cells grow larger in size, and the embryo's cells take in water and nutrients. The correct options are A and D.

The two processes that occur when the sea urchin embryo matures, according to the information presented, are:

The embryo's cells grow in size: During the embryo's growth and development, individual cells divide and grow in size, contributing to the organism's total growth.

The embryo's cells actively take in water and nutrients from the surrounding environment: As the embryo grows, its cells actively take in water and nutrients from the surrounding environment to support metabolic processes and offer the essential resources for growth and development.

Thus, choices A and D represent the proper processes that occur while the sea urchin embryo develops.

It depends on the quality of the elements upon the planet. They require carbon dioxide and sun light to photosynthesize and perform aerobic respiration with other components. However, there are some current planets that consist plants upon their surface.

Due to paralysis, the result is severe spinal injuries. This is often the case because the spine houses much of the central nervous system, which controls movement. Hence, option C is correct.

You might become paralyzed, and unable to move on your own when something interferes with the nerve impulses that muscles receive from the brain. Strokes, spinal cord injuries, and neurological diseases like multiple sclerosis are among the common causes of paralysis.

When you are unable to move your muscles voluntarily, you are said to be paralyzed. Paralysis results from nerve system issues.

Muscles receive messages from healthy nerves. This causes the muscles to contract. When you’re paralyzed, or have paralysis, you can’t move certain parts of your body.

Hence, it concludes that option C is correct.

Explanation:

If the goal of the exercise routine is to develop overall health rather than focusing on one specific improvement, a well-rounded approach that addresses various aspects of fitness would be ideal.

This would involve a combination of different types of exercises to promote cardiovascular health, muscular strength, flexibility, and overall well-being. From the given options, the best choices would be:

B. A variety of aerobic and anaerobic exercises: This option is important because it incorporates both cardiovascular exercises (aerobic) and strength-building exercises (anaerobic), ensuring a balanced approach to fitness.

A. A focus on the benefits of stretching: Stretching is important for maintaining flexibility and preventing injuries. Incorporating stretching exercises, such as static and dynamic stretches, can contribute to overall health and mobility.

D. An exercise that you have never tried before: While not as essential as the first two options, trying new exercises can add variety and excitement to your routine. It can also engage different muscle groups and challenge your body in new ways.

C. A single exercise with increasing intensity: While progressively increasing the intensity of a single exercise can be part of a fitness plan, focusing solely on a single exercise may not provide the diverse benefits that a combination of exercises can offer. Variety is key to a well-rounded fitness routine.

An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not.

Answer:

See explanation

Explanation:

The vertical axis corresponds to the pressure of a substance, while the horizontal axis corresponds to the temperature. The solid is the substance which contains particles of strong intermolecular force and compaction, typically ionic at a certain temperature, the liquid is the substance which contains relatively compact molecules, however lacks a particular arrangement. The gaseous substance is caused by particles with weak intermolecular forces, causing particle movement and collision with no arrangement whatsoever. The triple point as shown in the diagram, is the phrase on a diagram where each substance: solid, liquid and gas coexist. The critical point is the phase at which the/a substance is indistinguishable between liquid and gaseous states. A substance or elements state is highly dependent on its environment and it’s temperature, of which ultimately affects its kinetic energy within its particles. This is what the graph portrays and represents.

To solve this, we must be knowing each and everything related to atmosphere. Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.

The atmosphere is more than simply the beautiful sky above. The atmosphere is made up of numerous levels of gases that surround the planet.

The word "atmo," which meaning vapor, smoke, or fog in Greek, is the source of the atmosphere's name. "Sphere" comes from the Greek word sphaira, which meaning ball. The term "atmosphere" refers to a vapor ball. Thermosphere is the layer of the atmosphere has no definite outer limit. The thermosphere is located between 53 miles (85 kilometers) and 375 mile (600 kilometers).

Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.

The exosphere is the layer of the atmosphere that has no clear outer limit. The exosphere is the Earth's atmosphere's outermost layer, extending from the top of the thermosphere to the edge of space.

The exosphere, unlike the other layers of the atmosphere, gradually transitions into the vacuum of outer space with no clearly defined border.

The density and spread out of gas molecules in the exosphere are exceedingly low.

This area is made up mostly of relatively light gases like hydrogen and helium, and it is where satellites and other spacecraft circle the Earth.

Thus, the progressive reduction in density as the atmosphere merges into space accounts for the lack of a well-defined outer boundary.
