Answer:
1- The polar section of a phospholipid is the part with the phosphate group. This is sometimes called the polar head of the molecule.
2- The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

Answer
no.
Explanation:
we can only breathe normal oxygen. if we could breathe any other type of oxygen, we could breathe underwater.
but some animal lungs can do this though. but humans can't.

Warm-Up: What does it mean to be a prokaryotic cell? What
does it mean to be a Eukaryotic Cell? Which one came first?
(Think about the root words)
Answer:
eukrayotic cell l guess
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).
Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.
Eukaryotic Cells
In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.
A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions
why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Answer:
Deletion mutations can affect the entire base sequence.
Explanation:
Answer:
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

A: control center
B: storage place
C: energy processor
Answer:
Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa , vacuoles are cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.Explanation:
Answer: B: Storage place
Explanation: the vacuole stores food and any type of nutrient the cell may need to survive.

Compare how the nervous system and endocrine system work to send messages through the human body.
Answer:
Here is Your answer vote me as brainlist.
Explanation:
One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
The nervous system uses electrical and chemical signals to quickly send messages through the body, while the endocrine system uses hormones to gradually send messages through the bloodstream.
What is nervous and endocrine system?The nervous system uses electrical and chemical signals to transmit information rapidly and directly to specific target cells. This system is composed of neurons, which transmit impulses through the body, and specialized cells called neuroglia, which support and protect the neurons. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord and the PNS includes the nerves that extend out to the rest of the body.
The endocrine system, on the other hand, uses hormones to transmit information more slowly and diffusely throughout the body. Hormones are chemical messengers that are secreted by glands and travel through the bloodstream to target cells. The endocrine system includes a variety of glands, such as the pituitary gland, thyroid gland, and adrenal gland, that produce hormones that regulate various physiological processes, such as growth, metabolism, and reproduction.

The variety of different ways in which species within an ecosystem perform "jobs" that benefit the ecosystem and make it more resilient in the face of change is called ____________.
A. Ecosystem Diversity
B. Functional Diversity
C. Species Diversity
D. Genetic Diversity
E. Biological Diversity
Answer: B. Functional Diversity
Explanation:
Functional diversity can be defined as the component of the biodiversity which is concerned with the range of functions that organisms of an ecosystem perform to sustain their lives. These functionals are important for maintaining the stability in the ecosystem among the members. The organisms can change their functions depending upon the situation of the surrounding environment this is called functional adaptation.

How do calcium ions help amplify the signal?
HELP PLEASE!!!
Answer:
Calcium signaling is the use of calcium ions (Ca2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins. Ca2+ can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.

9. Explain why burning fossil fuels releases carbon dioxide.
10. Describe the path that carbon took to become a fossil fuel.
Answer:
4) The carbon dioxide comes from the animals and the oxygen comes from plants
7) Animals need to get their energy from other living things, but in order to do that said other living things need to have energy for the animals to get. Photosynthesis is the means by which plants and algae get their energy. Animals also need elemental oxygen,and photosynthesis produces this as a waste product as well
9) Fossil fuels consist mainly of carbon and hydrogen. When fossil fuels are combusted (burned), oxygen combines with carbon to form CO2 and with hydrogen to form water (H2O). These reactions release heat, which we use for energy

A.biosphere
B.hemisphere
C.geosphere
D.hydrosphere
Answer:
Should be D
Explanation:
The one that is not one of the four systems into which scientists divide earth is hemisphere. The correct option is B.
What are the spheres of Earth?
The four main subsystems of the Earth are the land, the water, the living beings, and the air. The term "spheres" refers to these four subsystems.
They are the "geosphere" (land), "hydrosphere" (water), "biosphere" (life) and "atmosphere," specifically (air).
The biosphere, geosphere, hydrosphere, and atmosphere are the spheres. Together, they are in charge of establishing and preserving the Earth's climate, geological processes, and life.
The main significance of the hydrosphere is that it supports a variety of life forms, is crucial to ecosystems, and regulates the atmosphere. All of the water on the Earth's surface is covered by the hydrosphere.
Thus, the correct option is B.
