As you observe an unknown cell under a microscope, you make the following observations. Need help ASAP. Thanks!

Answer:

D

Explanation:

During respiration oxygen is gotten from the atmosphere and carbon dioxide is given off

Answer:

Cell differentiation and cell division both work together by starting out with a somatic cell(basic cell) and cell differentiation gives it the specific instructions in the DNA to enable it to perform its function, then cell division comes in also known as mitosis, and it makes the cell with the whole package included with its function

Answer:

Animals can move, but plants cannot

Explanation:

Locomotion in humans and bipeds is accomplished through walking on legs. In other animals, it can be accomplished through walking on four limbs, flying, or swimming. In cells, cilia and flagella are used to move about. However, since plants are not capable of moving themselves, there is no locomotion of plant species.

Explanation:

If a cell became too large, an "information crisis" would occur. The cell has more trouble moving enough nutrients and wastes across the cell membrane. The rate at which food, oxygen, and water enter the cell, as well as wast products leave the cell, depends on the surface area of the cell and the cell's volume.

Answer:

Heterotroph. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.

Answer:

Weathering is the breaking down or dissolving of rocks and minerals on Earth's surface.

Explanation:

Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Answer:

the breaking down or dissolving of rocks and minerals on the surface of the Earth is known as weathering

Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.

Therefore two Lithium atoms bond with one oxygen atom to form Li2O

Answer:

The primary function of red blood cells is to transport oxygen to body cells and deliver carbon dioxide to the lungs.

Explanation:

Answer:

Hi there! The answer is, The function of red blood cells is to transport oxygen (O2).

Explanation:

Blood cells carry a protein called hemoglobin at the top of their disc surface. This protein allows oxygen to bind to it and thus creates an oxygen rich surface that is then carried throughout the body.

Answer: Expectation is that 75% of offspring will have the dominant phenotype, 25% the recessive phenotype.

Explanation: Pp x Pp gives expected offspring genotypes PP (25%), Pp (50%), pp (25%).

If P is dominant, the expectation for phenotype ‘P’ = 75% and for phenotype ‘p’ = 25%

Answer:

A. Ice Ages

Explanation:

These periodic changes on Earth are a result of the five major ICE AGES that have occurred throughout Earth's history

The five major Ice Ages that throughout the Earth's history we're the following:

1. the Huronian: this occurred around 2.4 billion years ago

2. Cryogenian: this followed Huronian age, and it occurred around the period of 850 million years

3. Agondean-Saharan: this major ice age occur around 460 million years ago.

4. Karoo this is a period of about 360 million years

5. Quaternary is the present age, and it has been in existence since about 2.6 million years ago till the moment

Hence, in this case, the correct answer is Ice Ages

Answer:

oxygen

Explanation:

oxygen isn't necessarily a characteristic of life. it's more like an aspect of life

Answer:

to break down protiens to amino acid monomers

Explanation:

Answer:

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Explanation:

Answer:

Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch

Answer: Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Evergreen plants keep their foliage, but their leaves and needles have a thick, waxy coatings to reduce water loss.

9. All of the above

Answer: An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
