During heavy exercise, the blood's volume flow rate is 5-10 times higher than when the body is at rest. Discuss different possible ways that a body can accomplish this
Answer: Two possible ways are aerobic respiration and anaerobic respiration.
Explanation:
Aerobic respiration: During aerobic respiration, the muscles of the body during vigorous exercise experience lack of oxygen as a result heart pumps faster to avail the necessary blood volume of oxygenated blood to all the muscles.
Anaerobic respiration: In the absence of oxygen the glucose stored in muscles is converted into lactic acid and this process avails energy for performing work but also causes cramps in muscles.
A) Name the membrane-bound enzyme that directly links the TCA cycle with the electron transport chain. Give its name in the TCA cycle and the electron transport chain. B) Name at least two other starting points for substrates used in the electron transport chain.C) Approximately how many protons are pumped for each of these electron transport chain starting points
Answer:
A). succinate dehydrogenase
B). glycolysis, TCA cycle
C). 10 and 6 proton respectively
Explanation:
Electron transport chain or the ETC may be defined as a electron transporters which is embedded into the inner membrane of the mitochondria which shuttles the electrons from the NADH and the FADH2 to the molecular oxygen.
A). The membrane-bound enzyme which directly links the TCA cycle with the electron transport chain is succinate dehydrogenase. It is called as the succinate-coenzyme Q reductase in the electron transport chain or the ETC.
B). The two other starting points for the substrates that is used in the electron transport chain are TCA cycle and the glycolysis.
C). For each of the NADH which enters the electron transport chain , there will be ten protons that is pumped into the IM space. And for the two FADH2, there will be six protons which is pumped into the IM space.
Which of the following statements is true?
A. The karyotypes for a male human and a female human will look exactly the same.
B. The number of chromosomes in all organisms is the same.
C. Sometimes, a single gene can influence many traits.
D. There are more chromosomes in a cell than there are genes.
Answer:
the answer is C
Explanation:
Sometimes, a single gene can influence many traits in an organism. This is possible due to gene interactions. Thus, the correct option is C.
What is Gene interaction?Genetic interaction is the set of functional association between different genes in an organism. Genetic interactions are the relationship is called as epistasis. Epistasis is the interaction of non-allelic genes where the effect of one gene in an organism is masked by another gene to result either in the suppression of the effect of that gene or they both combine to produce a new trait or character.
In epistasis, the gene which masks another gene is called as epistatic gene, and the gene whose expression is being masked is termed as hypostatic gene. Epistasis is also referred to as the inter-genic or inter-allelic gene interaction.
Therefore, the correct option is C.

(Q029) Which of the following statements is FALSE? Group of answer choices Formins promote the formation of unbranched actin filaments. Actin filaments are usually excluded from the cell cortex. Integrins are transmembrane proteins that can bind to the extracellular matrix. ARPs can promote the formation of branched actin filaments.
Answer:
- Actin filaments are usually excluded from the cell cortex
Explanation:
In eukaryotic cells, actin proteins polymerize in order to form filaments. These actin filaments can be localized beneath the plasma membrane, where they form a network that helps to provide mechanical support. This network localized on the inner face of the plasma membrane is called 'cell cortex', which is a specialized structure that is attached to the cell membrane by Ezrin, Radixin and Moesin (ERM) proteins. The cell cortex plays key roles by controlling the cell shape, cell morphogenesis and membrane behavior.
The statement "Actin filaments are usually excluded from the cell cortex" is false.
In point of fact, actin filaments are most frequently discovered in the cell cortex, which is a highly specialised region that is located close to the plasma membrane.
Actin filaments are abundant in the cell cortex, where they serve as a source of structural support and contribute significantly to the processes of cell shape maintenance, cell adhesion, and cell migration. Actin filaments play a pivotal part in these cellular functions.

identify the values and describe the attitudes that have contributed to pollution problems like those at herculaneum. how would you feel if you lived in herculaneum
Answer:
Herculaneum was an ancient town in Italy. Herculaneum has faced a lot of problems related to pollution that are contributed by humans.
During the eruption, the bones of hundreds of victims were left in the beach sites in the open air and the disintegration of dead bodies caused a lot of pollution in the area. Lead contamination is a common issue in Herculaneum that is creating environmental health hazards such as pollution. Plants and vegetation are rarely supported in Herculaneum people that increases the effects of pollution.
If i would have lived in Herculaneum, I would have felt suffocated in such an environment where there is a lot of pollution and I would try to plant some trees or vegetation nearby to support environmental health.

D. birds should not depend on fish for food. E. toxins can become concentrated in higher trophic level organisms.
Answer:
The correct answer is - option E. toxins can become concentrated in higher trophic level organisms.
Explanation:
Biomagnification is the accumulation of toxins and chemicals like DDT and other pesticides from food or water source and concentrated in the tissue of organisms than they normal or equilibrium.
DDT is more concentrated when it passes from a lower trophic level to higher trophic level or food chain as it slowley metabolize and excreted in these organism than lower trophic level organisms.

Answer:
Because in immunoassays, secondary antibodies are used to bind the primary antibody to assist in detection, sorting and purification of target antigens
Explanation:
Secondary antibodies are commonly used for the indirect detection of a target to which a specific primary antibody is first bound. It must be unique in term of exhibiting high specificity and sensitivity to both the antibody species as well as the isotype of the primary antibody being used. High quality secondary antibodies are paramount in achieving meaningful results

Why is it best to have a resting heart rate below 70 beats per minute?
Answer:
While the average adult's resting heart rate should range between 60 and 100 bpm, anything over 90 bpm is considered high. Generally speaking, lower heart rates are considered better as it means that the heart muscle doesn't have to work as hard to keep a strong, steady rhythm.

Chemical bonds tend to occur so that an atom gets a "full" valence shell. Two main types of bonds are ionic and
covalent. What is the main way these two types of bonds differ?
The two bonds differ mainly in the number of electrons shared. In covalent bonding, sharing always happens
in pairs, whereas in ionic bonding, single electrons can be shared.
The two bonds differ mainly in the whether whole or partial electrons are shared. In covalent
bonding, whole sharing always happens, whereas in ionic bonding, partial electrons can be shared.
In covalent bonding the two (or more) atoms bonded together share electrons. In ionic bonding, one atom
loses one (or more) electrons, while another atoms gains one (or more) electrons.
In ionic bonding the two (or more) atoms bonded together share electrons. In covalent bonding, one atom
loses one or more) electrons, while another atoms gains one or more) electrons.
Answer:
In covalent bonding the two (or more) atoms bonded together share electrons. In ionic bonding, one atom loses one (or more) electrons, while another atoms gains one (or more) electrons.
Explanation:
Atoms of molecules and elements come together chemically. The atoms of the same or different elements are joined together by means of chemical bonds, which are of different types depending on how it is formed. These chemical bonds include; covalent bonds, ionic bonds, hydrogen bonds etc.
- Covalent bonding occurs between atoms in such a way that the two or nore atoms involved share their valence electrons. Examples are CO, H2O etc
- On the contrary, ionic bonding also called electrovalent bond, is that type of bonding in which one atom transfers electrons to the other atom. Hence, the atom that loses electrons becomes more electropositive while the atom that accepts electrons become more electronegative. Examples are MgO, CaCl2 etc

Where is the gas-exchange surface in the bird respiratory system, i.e. where does oxygen enter the blood and carbon dioxide leave the blood
Answer:
the lungs
Explanation:
The avian respiratory system consists of three sets of organs that perform respiration: lungs (where gas exchange occurs), anterior air sacs and posterior air sacs. The lungs have static structures with surfaces that enable gas exchange, and air sacs that enable the unidirectional flow of air through the lungs. Birds have a very efficient respiratory system that obtains oxygen when they breathe in and breathe out. The inhaled air reaches the primary bronchus where enters to the lungs for gas exchange and also fills the air sacs.
Which factors involving the activities of people are a threat to biodiversity?
Answer:
Explanation:
Overexploitation of a species. Take elephants for example. Hunters hunt them down for ivory. Say that there was a disease going around elephants, that is incredibly deadly. Take Bobby the elephant. Bobby the elephant is one of the few that has natural immunity to the virus, and if he were to reproduce he could help save the elephant population. If Bobby was hunted down before he reproduces, the population of elephants are put in danger. Also killing a large portion of a species will make it so that the animals in that species have limited mating partners, which can restrict biodiversity
