Transfer RNA has __________ bases attached to one end of the molecule and an amino acid to the other.
Answer:
Nitrogenous
Explanation:
Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.
The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.
N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.
Forms of inheritance that do not follow typical Mendelian patterns and that appear to be more influenced by the parent contributing the most cytoplasm to the embryo are grouped under the general heading of ________.
Answer:
Extrachromosomal or cytoplasmic inheritance
Explanation:
Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.
This form of inheritance lays in genes that are out of the nucleus. Information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.
Although mitochondrial inheritance is mostly maternal, recent studies have demonstrated that it might also be paternal.
Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.

10 differences between animal cells and plant cells
Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.the heat of the sun is received by conduction true or false

Because the flow speed in your capillaries is much less than in the aorta, the total cross-section area of the capillaries considered together must be much larger than that of the aorta. Given the flow speeds noted, the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of approximately what diameter
Answer:
Diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm.
Explanation:
The diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm which is the main reason for higher flow speed of the blood in the aorta as well as more blood is transported in the aorta. If the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of aorta then the flow speed of both is similar due to similar area.

There are 3 basic structural types of joints: fibrous, cartilaginous, and synovial. If a joint does NOT move, you can assume that it's either ___ or ___. (Choose 2).
Answer:
The correct answer is - fibrous, cartilaginous.
Explanation:
In the body, there are joints named after the type of tissue attached to them and these joints are:
1. fibrous joints - these are connected with dense connected tissues and called immovable or fixed joints.
2.cartilaginous joints - these are joined by cartilage tissue. These joints are also not able to move freely.
3. synovial joints are known as movable joints and can move freely. These are present in a fluid-filled capsule for better movement.
For young men of age 20, there have been 150 rounds of DNA replication during sperm production as compared to only 23 rounds for a woman of age 20. That is a 6.5-fold greater number of cell divisions and proportionately greater opportunity for new point mutations. Yet, on average, 20-year-old men contribute only about twice as many new point mutations to their offspring as do women. How can you explain this discrepancy
Answer:
A plausible hypothesis is that deleterious germline mutations in sperm cells are removed by natural selection since sperms have to compete to fertilize the egg
Explanation:
Sperm cells need to travel through the cervix in order to reach the uterus and fertilize the egg. During this process (which is called 'fertilization'), approximately 300 million sperm cells have to compete in a race to reach an egg. During fertilization, the majority of sperm cells die off quickly because male germinal cells carry mutations that lead to abnormalities (e.g., many sperms have double heads, others no tail, etc). The sperm cells are considered to be physiologically weak because their normal functions can be easily disrupted by mutations and, simultaneously, they are under strong selective pressure to be selected during the sperm race. In consequence, deleterious germline male mutations are expected to be eliminated by natural selection, thereby sperms are selected before fertilization so only the strongest ones can compete in the race to fuse with the egg cell and thus develop one zygote.

When a muscle relaxes: Question 10 options: crossbridges form and muscle extensibility returns the muscle to rest length. crossbridges form and muscle elasticity returns the muscle to rest length. crossbridges stop forming and muscle elasticity returns the muscle to rest length. crossbridges stop forming and muscle extensibility returns the muscle to rest length
Answer:
When a muscle relaxes,
crossbridges stop forming and muscle elasticity returns the muscle to rest length.
Explanation:
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation will also occur when ATP is no longer available.
In interstitial growth of cartilage ______. Multiple choice question. only new cells are produced only new matrix is produced news cells and new matrix are produced
Answer:
The correct answer is ''news cells and new matrix are produced''
Explanation:
Interstitial growth consists of the production of new layers of cartilage in the inner layer of the perichondrium. This process occurs because chondrocytes meet in the form of small groups, called isogens or cell nests, they are capable of dividing and the cartilaginous matrix is distensible. Daughter cells initially occupy the same gap but as they secrete new intercellular matrix they separate. These daughter cells can divide again, forming so-called isogenic groups, which are frequently found in growing cartilage.

Which of the following factors affecting population growth is density
independent?
A. Competition
B. Disease
C. Natural disaster
D. Predation
C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.
How Natural disasters reduce population sizes?Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.
Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.
Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.
On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.
Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.
Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.

Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.
