what is true of a fossil that is classified as a transitional form?

Answer:

The oxygen did not build up in the atmosphere for a long time, since it was absorbed by rocks that could be easily oxidized (rusted). To this day, most of the oxygen produced over time is locked up in the ancient "banded rock" and "red bed" rock formations found in ancient sedimentary rock.

Different oganelles do their own function.

The structures of organelles differ because the structures of  organelles are related to their functions.

An organelle is a subcellular structure that has one or more specific functions in a cell, such as an organelle in the body. The most important cell organelles are the nuclei, which store genetic information.

Organelles are small structures in the cytoplasm that perform functions necessary to maintain homeostasis in the cell. They are involved in many processes, such as energy production, the formation of proteins and secretions, the destruction of toxins, and responding to external signals.

Examples of membrane-bound organelles include the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.

Answer:DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.

Explanation:

DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.  DNA could get damaged because of the osmotic nature of cytoplasm. Therefore, option (C) is correct to mitigate he damage.

The proteins are produced by cells by the transcription and translation of certain genes from their DNA into molecules of messenger RNA (mRNA), chains of amino acids, and finally fully functioning proteins.

The DNA would need to go to the cytoplasm in order to directly make proteins. Because of the osmotic properties of cytoplasm, DNA may become damaged during the translocation process. The cellular machinery does not directly make proteins from DNA in order to reduce the harm.

The gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.

The neurons are the smallest units of the nervous system. They are equally referred to as the nerve cells.

The presynaptic neurons that receives the fired action potential through its axon terminals.

This leads to release of neurotransmitters found in the synaptic vesicles of the presynaptic neurons.

These neurotransmitter are released into the physical gap between the presynaptic and postsynaptic neurons called the Synaptic cleft.

The neurotransmitters are then received by the postsynaptic neurons.

Therefore, the gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.

Explanation:

etc uses oxygen

photosynthesis uses carbon dioxide

The best  statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.

Photosynthesis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.

Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products. Splitting water into oxygen gas, hydrogen ions and electrons produces the energy for subsequent electron and proton transport and provides the energy to produce the sugars the plant needs.

The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.

Therefore, The best  statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.

Answer:

the answer is epimysium

Explanation:

The connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option as it is composed of dense, irregular connective tissue and serves to protect the muscle.

The epimysium plays a role in transmitting force from the muscle to the surrounding structures and connects to the tendons and other connective tissues that attach the muscle to bone and other structures, and the epimysium is just one of the three connective tissue layers that make up the structure of a skeletal muscle; the other two layers are the perimysium and the endomysium, and together, these three layers of connective tissue provide the necessary structural support for skeletal muscles to function properly.

Hence, the connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option.

Answer:

a. Rifts

Explanation:

A fault (c) happens at all plate boundaries, so while this is true, it is not the most correct. A subudction zone (b) is where Earth's tectonic plates dive down into the mantle, so this does not answer our question. A rift, in general, is a crack, split, or break in something. A rift in plate tectonics is when plates are moving apart from each other, caused be tension, so a is our answer.

Differentiation in plants and animals involves the specialization of cells for specific functions, and it results in the development of different tissues and organs.

Differentiation refers to the process by which cells become specialized in structure and function. In plants and animals, this process occurs during development and results in the formation of different types of cells, tissues, and organs.

During differentiation, cells undergo changes in gene expression, which leads to the production of different types of proteins and other molecules. These changes can be triggered by various signals, such as hormones, growth factors, and environmental cues.

In animals, differentiation occurs during embryonic development and results in the formation of different types of tissues, such as muscle, bone, and nerve tissue. In plants, differentiation occurs during both embryonic development and growth and results in the formation of different types of tissues, such as root tissue, leaf tissue, and stem tissue.
