Answer:
Glycolysis and Krebs cycle.
Explanation:
During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.
Why are scientific journals considered a superior resource compared to other sources of scientific information?
I NEED HELP
Scientific journals are regarded as more superior due to the fact that they are peer reviewed.
What this means is that before a scientific journal would be approved for publishing, it first has to be reviewed by some experts in that scientific field.
What these peers do is to Approve the journal, make suggestion to the work, or they can decide to reject the work if they find it unsatisfactory.

The following illustration shows a food web for a kelp forest off of the coast of California. What do you predict would happen to the kelp population if the sea otter population declined?
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
The kelp population would increase: sea otters eat urchins, but not exclusively.
The kelp population would remain unchanged; sea otters do not eat the kelp.
The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.
Answer:
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Explanation:
The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.
Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.
Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

After phosphates and nitrates have entered a water
system, identify the correct steps of Eutrophication.
I. Oxygen levels drop
II. Underwater plants die
III. Fish and invertebrates die
IV. Algae grows rapidly
A. II, III, IV, I
B. IV, II, I, III
C. I, III, IV, II
D. III, II, I, IV
After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
Algal bloom: the nutrients facilitate the rapid growth of algaeThe bloom of algal species results in the death of underwater plants as a result of inadequate light.The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxiaTherefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

4. Trichomoniasis
5. Crabs
6. Genital herpes
7. HPV
Explanation:
STD is an acronym for sexually transmitted disease and it can be defined as diseases that are easily transmissible or contractable from another person through sexual intercourse. Thus, STD spread from an infected person to an uninfected person while engaging in unprotected sexual intercourse. Some examples of STDs are gonorrhea, chlamydia, syphilis, HIV, HPV, etc.
Generally, contracting STDs has a detrimental effect to a patient because it causes an opening (break) or sore in the body of the carrier (patient) and as such making them vulnerable to diseases that are spread through bodily fluids e.g human immunodeficiency virus (HIV), Hepatitis, staphylococcus, AIDS, etc.
1. Syphilis: can cause sores, rashes, dementia, or blindness.
2. Gonorrhea: can cause burning urination and infertility
3. Chlamydia: similar to gonorrhea but more likely to be carried unknowingly
4. Trichomoniasis: parasitic STD causing genital irritation and mild discharge.
5. Crabs: pubic lice that cause itching.
6. Genital herpes: untreatable STD causing periodic outbreaks of blisters
7. HPV: can cause genital warts or cervical cancer. HPV is an abbreviation for human papillomavirus and it's a virus that causes most common sexually transmitted infection, giving rise to skin or mucous membrane growths (warts).
Answer:
1) syphilis

In a separate maddyase experiment using (Et)-10nM, the reaction velocity is measured as 3uMS. What is the substrate concentration used in the experiment
Answer: hello your question has some missing data attached below is the missing data
Applying the Michaelis-Menten Equation
An enzyme is found that catalyzes the reaction X ⇋ Y Researchers find that kcat for this enzyme is 600s^-1 and carry out several additional experiments.
answer :
substrate concentration [ x ] = 10⁻⁵ M
Explanation:
Given data:
[Et ] = 10 * 10⁻⁹ M ,
Reaction velocity ( V₀ ) = 3* 10⁻⁶ Ms⁻¹
applying Michaelis-Menten Equation
= 3* 10⁻⁶ = [tex]\frac{600 *10*10^{-9} * (X) }{10^{-5} + (X) }[/tex] ,
= ( 3 * 10⁻⁶ )( x ) + ( 3 * 10⁻¹¹ ) = ( 6 * 10⁻⁶ ) ( x )
hence the substrate concentration [ x ] = 10⁻⁵ M
suggest TWO reasons why fewer birds and other small animals can survive in the areas left after trees have been cut down
Answer:
One is that they migrate to more fertile places.
Second, some animals may die because they can't stand the conditions of treelessness. But some animals can survive. because of adaptation
Explanation:
Removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat
What is Deforestation?Deforestation also known as forest clearance is defined as the removal of forest or stands of trees from land that is converted to non-forest use in which forest land is converted into farms, ranches or urban may involve converting to use. The most concentrated deforestation occurs in tropical rainforests.
It occurs when humans remove or thin forests for timber or use land where trees stand for crops, grazing, extraction such as mining, oil, or gas, or as populations grow and people move. Development takes place in the form of migration.
Wildlife habitats are fragmented due to deforestation, where native species have to live on remaining habitat islands that are surrounded by disturbed land being used for agriculture and other uses.
Thus, removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat

The term bycatch or incidental catch refers to ________. non-target species that are caught along with commercial species species harvested for industrial purposes species raised in aquaculture settings species caught as part of traditional fisheries krill and other shellfish
Answer:
The correct answer is ''non-target species that are caught along with commercial species''
Explanation:
Bycatch refers to bycatch organisms that are not targeted by the fishery. Occurs inadvertently in fishing gear, all fisheries have some unwanted bycatch. Species with little or no commercial value, juvenile stages, or discarded gravid females of the target species (s) are generally included here. These incidental catches can be marginal when fishing is carried out with selective or very substantial gear, when the gear used indiscriminately catches everything that comes along its route. In marine fisheries, it causes injury or death to mammals, birds, turtles, fish, elasmobranchs, and invertebrates.

Give the functions of the following parts of the respiratory system - Nostril - trachea - bronchiole - alveoli - pharynx - larynx - lungs - ribs - diaphragm
Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.

Explanation:
1）Fishing boats have decreased the number of herring in the sea. Explain why that could affect the number of offspring puffins can raise.
2） Which animals have a bigger food supply now there are fewer herrings?
3） Global warming is expected to reduce the biomass of phytoplankton in the oceans. What effect will that have on the rest of the food web?
Explanation:
1) When the number of herrings decrease, the food available for the puffins decrease and therefore they will not be able to feed their offspring. This will cause the number of offspring to decrease.
2) Any other animal(s) which hunts and eats the same prey as a herring will now have a bigger food supply.
3) When the biomass of phytoplankton decrease, the next animal in the food web will not have any food and their numbers will decrease, decreasing the number of the animals next in the web, as they too lose their food. This will continue for the rest of the food web and the number of animals will decrease.
