When a star runs out of Hydrogen fuel, the core shrinks down because?
Answer:
When the star runs out of hydrogen the core's temperature decreases so the thermal pressure decreases as well. With a result of the core becoming less efficient to hold up the rest of the star's weight. The core and the gas around it starts shrinking As this happens, the gas in the core and shell around it heats up. Then the star is becomes a supernova.

Distinguish lobopodia, filipodia, reticulopodia, and axopodia
Answer:
Lobopodia, characteristic of Amoeba, are blunt and fingerlike; filopodia are slender and tapering, occasionally forming simple, branched networks; reticulopodia, found in the foraminiferans, are branching filaments that fuse to form food traps; and axopodia, characteristic of the actinopods, are long and sticky.

Does DNA control RNA?
Answer:
RNA is usually synthesized from DNA.
Answer:
RNA is usually synthesized from DNA. The synthesis usually requires one or more enzymes like RNA polymerase. The DNA strand is used as a template or guide on which the RNA is formed
In reality, there is much more to the RNA story. The central dogma of molecular biology suggests that DNA maintains the information to encode all of our proteins, and that three different types of RNA rather passively convert this code into polypeptides.

The concave surface of the lungs where blood vessels, lymphatic vessels, nerves and the primary bronchi enter and leave contains a slit called the HILUM. It is also known as the root region.
The hilum (root region) is the point at which bronchi, pulmonary arteries and pulmonary veins enter into the lung.
Each hilum (left and right) has a pulmonary artery, pulmonary veins, and bronchial arteries.
The hilum or root region connects the lungs to supporting structures where pulmonary vessels enter and exit the lungs.

You meet a man on the street. He has 10 fingers and 10 toes. What is his genotype with respect to the polydactyly trait
Answer:
woman dd, man Dd
Explanation:
Polydactyly is a dominant trait that results in extra fingers and toes in humans. A man with polydactyly marries a woman with 10 fingers and toes. They have a child that has a normal number of digits. The phenotype of the man's father is unknown, but his mother has a normal phenotype. What are the genotypes of the married couple? (D = polydactyly allele; d = wild type allele)
What would happen if the cell membrane only had 1 layer of phospholipids?
Answer:
If phospholipid bilayer diffusion is normally negligible, there will be tissues (largely lacking in transporters that may be expressed elsewhere) which, despite the relative functional similarity of their phospholipids, are very poor at taking up drugs: the blood–brain [33], blood–testis [34], and blood–retina
Explanation:
The cell membrane has two layers for phospholipids because of its hydrophobic and hydrophilic nature as the cell has to give entry to both the molecules therefore the bi layer makes this the possible option.
What is the reason for more stability for the 1 layer of phospholipids ?The single layer of phoshpholipids makes it more easier to maintain phospholipids' stability because the membrane phospholipids will interact with the hydrocarbons of oil molecules via van der waals interactions.
The basic cell structure is well protected with the help of membrane and the various transportation activities along with the cellular processes takes place via the phospholipids because of their hydrophobic and hydrophilic interactions between the molecules.
Thus, 1 layer will definitely add on stability but the interaction and cellular activities will take place through phospholipids interactions.

Chemosythesis involves inorganic chemicals therefore, light photons are not required during chemosynthesis.
Chemosynthesis refers to the process by which some organism obtain food from inorganic chemicals rather than from light. There are many chemosynthetic bacteria that obtain food by the metabolism of methane, hydrogen sulfide or carbon dioxide.
Light photons are not required for chemosynthesis. It is only necessary during photosynthesis.

What does "endemic" mean? Why are there so many different types of endemic plants in California?
Answer:
Endemic: Belonging or native to a particular people or country
Due to specific chemical and physical characteristics of the soils, these habitats are nutrient-poor, and this has led to the establishment of a highly specialized and diverse flora. It has been estimated that serpentine endemic plant species represent 10 percent of the California Floristic Province's endemics.
Explanation:
for example, something is endemic if it is found in a particular geographic area, population or region
aminoacyl-trna synthetase is an enzyme whose function is to _____.
Answer:plays a critical role in protein synthesis,
Explanation:
Aminoacyl-tRNA synthetase is an enzyme whose function is to attach the appropriate amino acid to its corresponding transfer RNA (tRNA) molecule, creating an aminoacyl-tRNA complex that will be used in protein synthesis.
What is Aminoacylation?Aminoacylation, also known as tRNA charging, is a biochemical process in which an amino acid is attached to its corresponding transfer RNA (tRNA) molecule. This process is catalyzed by the enzyme aminoacyl-tRNA synthetase, which recognizes the specific amino acid and the corresponding tRNA molecule that carries the anticodon sequence for that amino acid.
Aminoacylation is a crucial step in the process of protein synthesis, as the charged tRNA molecule brings the amino acid to the ribosome during translation, allowing the amino acid to be incorporated into the growing polypeptide chain.
The accuracy and efficiency of aminoacylation are critical for ensuring that proteins are correctly synthesized, as errors in aminoacylation can lead to the misincorporation of amino acids and the synthesis of non-functional or improperly folded proteins.

Information about the four organisms can be found on the Internet. Use credible websites to find answers to the questions you developed in part A. Based on this data, draw your own dichotomous key.
Based on the key you created, do you think some of the organisms are more closely related than others? Explain your answer.
Part 1 was this:A dichotomous key works on the principle of asking yes-or-no questions about the organism. To identify it, the answers for that organism are then compared to existing organisms to identify it. Prepare a list of four to five questions about each of the organisms listed below to help you create your own key. For each question, make sure the answer isn’t the same for all four organisms. For example, Does the organism have cells? would be an inappropriate question, because all the organisms have cells.

This may not exactly align with your answer but here's the key and I wrote for Part E:
Explanation:
Part E: Yes, I think that there are some closely related species of organisms that cannot be identified with a dichotomous key. Dichotomous key is used to classify objects or organisms based on its physical characteristics. Because of that limitation, there are species that may be related according to the dichotomous key but are in fact not or its relation is very minimal whereas there are organisms that may seem unrelated based on their physical characteristics but are actually from the same ancestors.

A recessive X-linked trait is a trait accompanied with mutations on the gene on the X chromosomes.
If a normal couple then have a child that is color-blind. At least one member of the couple's families is colorblind, this is most likely the mother's father.
Since the couple are normal, it mean the father is not a carrier as he has only one X chromosome and the mother is a carrier with one normal X and the other affected.Most of the time a male carrying the trait is affected meaning for the woman to be a carrier she must have gotten it from her father who is color-blind.Learn more: https://brainly.com/question/13204877

The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the A) atrial systole. B) early diastolic filling phase. C) late diastolic filling phase. D) systolic ejection phase. E) dicrotic phase.
The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.
The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.
This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.
The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.
The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.
