The hypothesis that whales evolved from land-dwelling ancestors is supported by __________. ANSWER Unselected molecular comparisons of whales and fish Unselected historical accounts of walking whales Unselected the ability of captive whales to be trained to walk Unselected fossils of extinct whales that had increasingly reduced hind limbs Unselected evidence from the current biogeographic distribution of whales Unselected I DON'T KNOW YET
Answer:
The answer is "Third choice".
Explanation:
Fossils are a great source of evidence about whales' forebears. It demonstrates, for instance, that a land mammal lived 50 million to 700 years ago. Whales evolved from such marine residents were thought by scientists. Scientists. This and more cells from a fossil can be said, so the concept that whales evolved from ancestors of land is reinforced by an extinct whale which has shortened the hind limbs evermore.
Describe movement of molecules to maintain a healthy cell environment. Explain in details
Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.

Highlight all the atoms of the four functional groups, but do not highlight any bonds. When you click on each atom, it will change color. To deselect an atom, click on it again. Before you submit, check that you have not selected any bonds.
Hi. You did not submit any image, table or description of a molecule for the functional groups to be pointed out. This makes it impossible for your question to be answered. However, I will try to help you as best I can.
A functional group is a set of atoms of different chemical elements that take the place of a hydrogen atom that was part of a hydrocarbon (it is a molecule composed of carbon and hydrogen atoms). The most common functional group is −OH, but you also often encounter −SH, −NH2, and −OPO2−3 functional groups.

Which part of the neuron below is indicated by the arrow, and what is its function?
The long section of a neuron that includes structures that wrap around the neuron are indicated by the arrow.
- The myelin sheath releases neurotransmitters so that electrical impulses can be transferred.
- The myelin sheath protects and transmits electrical impulses faster.
- The node of Ranvier transmits electrical impulses faster.
- The node of Ranvier transfers information across a gap.
Answer:
the arrow points to an axon
Explanation:
Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.
Answer:
B: The myelin sheath protects and transmits electrical impulses faster.
Explanation:

which of the samples shown below are photosynthetic
Option B. Samples ACD Are photosynthetic
What does it mean to be photosyntheticTo be photosynthetic means to possess the ability to carry out photosynthesis, a vital process in which organisms, typically plants, algae, and some bacteria, use sunlight, carbon dioxide, and water to synthesize organic compounds, particularly glucose, and release oxygen as a byproduct.
Photosynthesis occurs in specialized cell structures called chloroplasts, which contain chlorophyll and other pigments that capture light energy. These pigments absorb light, primarily in the visible spectrum, and convert it into chemical energy through a series of biochemical reactions.

Adrenergic receptors Select one: a. can be activated by the release of epinephrine. b. have two structural forms - muscarinic and nicotinic. c. when activated stimulate skeletal muscles to contract. d. can be found in both the sympathetic and parasympathetic divisions. e. are activated by the release of acetylcholine.
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

Molecules on the outer surface of a microorganism act as____
The immunostimulants act as those molecules that are found on the outer surface of the microforms.
What are microsorgams ?The microorganisms are those organisms that can only be seen through the microscope and include the bacteria, the protozoa, the algae, and the fungi.
The virus is not considerd to be living and has a single cell or may form a colony of cells. The unseen microbial life is scripted in the 6th century BC. As these microorganisms have a single-celled life they are more diverse.
The presence of the immunostimulants on the body of the micro organs tells about the outer surface of these microorganisms.

Cellular respiration definition ?
Answer:
cellular Respiration is that cells use oxygen in mitochondria to make ATP and GTP for cells
Answer:
Cellular respiration occurs when cells utilize oxygen in their mitochondria to produce ATP and GTP.
Cellular respiration is a series of reactions that occur under aerobic conditions and result in the production of large amounts of ATP.
Explanation:
Glucose, the basic building block for starch and many sugars are one of the main sources of energy in our diet. Its oxidation can be divided into three phases in the respiration of the cells: glycolysis, the cancer cycle, and the electron transport system.
Aerobic breathing uses eukaryotes to generate energy, including all multicellular organisms and some single-cell organisms. Aerobic breathing uses oxygen – a powerful, in-kind electron acceptor.
Aerobic breathing is an extraordinarily effective process that enables eukaryotes to have complicated life and active lifestyles. It also means however that they need a continuous supply of oxygen or that they cannot get the energy to stay alive.
Other forms of respiration, which are slightly less efficient, can be used by procharian organizations such as bacteria and archaebacteria. They can therefore live in environments in which eukaryotic organisms cannot live because they do not need oxygen.

In the plasma membrane, the phospholipid heads Group of answer choices are hydrophilic and face inward, shielded from water. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane.
Answer:
are hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The plasma membrane is structurally made up of a phospholipid bilayer, which is amphipathic in natire. This means that the phospholipid layer of the plasma membrane consists of phosphate head that is water loving or hydrophilic in nature and a lipid tail that is water fearing or hydrophobic in nature.
Since the phosphate head is HYDROPHILIC, they face outward toward the aqueous (water) solution on both sides of the membrane. This allows the phosphate head to attract water molecules.
