Choose the phrase that best describes the role of viral surface proteins or spikes! -Inject viral nucleic acid into host cell -Provide means for viruses to exchange nucleic acid -Enable replication of the viral nucleic acid -Provide means of attachment to host cell surface -Allow viruses to bind to each other
Answers
The role of viral surface proteins or spikes is to provide a means of attachment to the host cell surface.
Viral surface proteins, also known as spikes, play a crucial role in the attachment and entry of viruses into host cells. These spikes are usually located on the outer surface of the viral envelope and are composed of proteins that are specific to each type of virus. The spikes enable viruses to bind to specific receptors on the surface of host cells, facilitating the initial attachment of the virus to the cell.
The attachment of viral spikes to host cell receptors is often the first step in the viral infection process. Once the virus has attached to the host cell, it can then proceed to enter the cell and release its genetic material.
However, it's important to note that the primary function of viral spikes is to mediate attachment and entry, rather than directly facilitating the injection or replication of viral nucleic acid.

The question for this is: Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Energy is also transformed from one type to another. Describe what happens to these four substances, light energy, and chemical energy during photosynthesis. Then write a simple equation for the substances and another for energy, using words and arrows to illustrate these changes.
My friends answer is:
Photosynthesis is the process by which plants use light energy to convert water and carbon dioxide into sugars and oxygen. During photosynthesis, light energy is absorbed by the plant and converted into chemical energy. The water and carbon dioxide are broken down into their component parts, and the oxygen is released into the atmosphere. The sugars are stored in the plant for later use. The equation for photosynthesis can be represented as light energy + water + carbon dioxide → sugars + oxygen. The equation for energy transformation can be represented as light energy → chemical energy.

Answers
Plants employ the process of photosynthesis to transform water and carbon dioxide into carbohydrates and oxygen.
Light energy is absorbed by the plant during photosynthesis and transformed into chemical energy. The oxygen is released into the environment, while the water and carbon dioxide are disintegrated into their component elements.
In the plant, the sugars are kept for future use. It is possible to write the photosynthesis equation as follows:
Light energy + water + carbon dioxide → sugars + oxygen.
Light energy → chemical energy can be used to describe the energy transformation equation.

PLS HELP ASAP Select the word that means how easily water can move through a substance. Lesson 2.03 o particles permeability porosity
Answers
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
The water can easily move through a substance and it is called permeability. Hence, option B is correct.
What is permeability?The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.
The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.
The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

A locus encodes different genes in different individuals of the same species.
True
False
Answers
False. A locus is a specific physical location on a chromosome that can encode one or more genes.
However, the same locus typically encodes the same gene or genes in all individuals of a given species. There can be genetic variation between individuals at a given locus due to differences in the DNA sequence, but this does not result in the encoding of different genes.A locus is a specific location on a chromosome where a particular gene is located. Each gene is typically found at a specific locus, and the same gene is usually located at the same locus in all individuals of a given species. For example, in humans, the gene for the protein hemoglobin is located on chromosome 11, and all humans have this gene at the same locus on chromosome 11.
However, there can be genetic variation between individuals at a given locus. This variation can occur through differences in the DNA sequence, such as single nucleotide polymorphisms (SNPs) or insertions/deletions (indels). This variation can affect the function of the gene, and can also be associated with differences in traits between individuals. However, these differences in sequence do not result in the encoding of different genes at the same locus in different individuals of the same species.

The high osmolarity of the renal medulla is maintained by all of the following except B. the spatial arrangement of juxtamedullary nephrons.
Osmolality refers back to the awareness of dissolved particles of chemicals and minerals including sodium and other electrolytes in our serum. higher osmolality means we got more debris on your serum. lower osmolality approach the debris is greater diluted.
A juxtamedullary nephron is a nephron whose renal corpuscle is near the medulla, and whose proximal convoluted tubule and its related loop of Henle occur deeper within the medulla than the opposite type of nephron, the cortical nephron.
The main characteristic of the juxtamedullary nephron is to pay attention or dilute urine. The absorption of more water via the vasa recta may additionally produce extra focused urine while the much less reabsorption of water may also produce diluted urine.

is actually three separate bones: the ilium, ischium, and pubis? In most of you
they are just now beginning to fuse together.” Then, while holding a femur she
explained that “the ends of the long bones fuse to the shaft at various ages,
and for the femur, this is between 14 and 21 years, and for the clavicle, it
occurs between 20 and 30 years of age. Why do you think the skeleton starts off
with more separate bones and fuses them along the life span? Are there any
advantages to either unfused or fused bones?
Answers
The skeleton(hipbones) starts off with more separate bones and fuses them along the life span to allow for complete development of underlying organs and for flexibility needed during the birth of the developing foetus. This flexibility is the advantage of the unfused bone before birth.
What is skeleton?Skeleton is defined as the hard structures that makes up the musculoskeletal system specific f the body which provides support and ability for movement.
During the development of the foetus, not all the bones of the body are fused especially the bones of the skull and the bones of the hip. This leads to the total number of bones in a baby being 300 bones and that of an adult is 206.
After birth, the bones of an infant undergoes ossification. That is to say that the skull and hip bones which where separate before birth fuses together and forms a stronger structure.

Answers
14 ATP molecules can be synthesized by the cell for each molecule of pyruvate oxidized to carbon dioxide and water.
Normally a cell produces 38 ATP for one molecule of glucose oxidized. But if the cell is able to synthesize 30 ATP molecules for each molecule of glucose completely oxidized by carbon outside and water. This happens through the glycolysis pathway, where 1 molecule of glucose is broken down to 2 molecules of pyruvate. Now the ATP goes directly through the glycolysis, so for each pyruvate molecule, 14 ATP molecules are produced. Glycolysis occurs in both aerobic and anaerobic states. In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the production of 32 ATP molecules.
