NUMBER 13 PLEASEEE!!!!!

I will put the events in order and further explain what happens to gaseous exchange during exercise.

During exercise,

- Blood CO2 increases,

- Blood becomes more acidic-PH decreases below the set point,

- Brain stem detects PH change,

- Brain cell signals muscles in the diaphragm and rib cage,

- Breathing level increases,

- Amount of CO2 exhaled increases,

- Blood PH returns to the set point.

During exercise,the cells of the muscles respite more than when the body is at rest.Heart rate increases abd,more oxygen is used or required and more CO2 is exhaled.

The rate and depth of breathing increases and this is in a bid for the body to compensate by making sore that more oxygen is absorbed into the blood as well as remove more carbondioxide

When CO2 combines with water, carbonic acid is formed,this makes the blood to become acidic.

Therefore,when CO2 is present in the blood,it decreases the blood PH and an excess of it (PH less than 7.35) will result in Acidosis.

B. It shows how the rocket performs in the atmosphere, but not in space

Explanation:

This is actually not as complicated as it may seem. Wind tunnels are a way that scientists and students can see how wind can affect rockets. The Wright brothers used a wind tunnel to test there model planes. The reason it has limitations is there is no wind is space because there is no gravity which means there is no particles that make up weather and wind. Wind tunnels help us know how the rocket will perform on the earth, but not in space.

Answer:

cause plants do not move from there places and need to make there own food so he can survive.. that is why they need a cell with all necessary and animals can hunt or eat plants which means he just need the cells to produce energy and movements

Explanation:

Plants and animals have different types of cells because they possess different characteristics, modes of nutrition, adaptation, metabolic activities, etc.

Plant cells may be defined as the type of eukaryotic cell that has a well-defined nucleus and other membrane-bound cell organelles. These cells are the basic unit of life in organisms of the kingdom Plantae.

Animal cells are also of eukaryotic nature but both shares a huge difference in the composition and manufacturing of cells. Plants have to synthesize their own food with the help of sunlight so they possess chloroplast while animal cells are of the heterotrophic mode of nutrition where they derive their food from plants and their products.

Plants are typically immobile in nature so they have required some sorts of cells that provide them stability in their survival. While animals need some motility cells like bones and other tissues that provide the movement.

Therefore, on the basis of structural dissimilarities, mode of nutrition, adaptation, metabolic activities, etc. plants, and animals have different types of cells.

The process in the image is ( C ) : Water, carbon dioxide and light are inputs while oxygen and glucose are outputs

The process represented in the diagram is photosynthesis because Photosynthesis is the process whereby green plants makes use of water and Carbon dioxide from the atmosphere in the presence of light  to produce its food and also producing oxygen as its by product in the process

Photosynthesis :

H₂0 + CO₂  + light energy ----->  C₆H₁₂O₆ + O₂

Hence we can conclude that the  process in the image is Water, carbon dioxide and light are inputs while oxygen and glucose are outputs

Answer:

Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.There are three basic metabolism types: ectomorph, mesomorph, and endomorph – definitely words you probably don't use in your normal, day-to-day conversations.If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

Answer:

arrive at a conclusion

Explanation:

The analysis of data gathered during a particular experiment is necessary in order to arrive at a conclusion that will address the aim of the experiment.

Without data analysis, valid conclusions about the experiment cannot be made and what the experimenter would have is just raw data that cannot say or answer anything about the experiment.

The data collected from experiments can be analyzed in two ways:

In descriptive data analysis, the collected data is summarized, arranged, or described in such a way that a pattern can be seen at a glance. It includes tables, charts, histograms, etc.

In inferential data analysis, the collected data is treated in such a way that an inference can be arrived at based on the study. This includes testing for a significant difference between means, testing for the goodness of fits, correlations, etc.

The difference between past time focus and present time focus is that present time focus refers to the moment we are living in, the moment we are going to now. The past focus is that we are paying attention to the things that we have experienced in the past. The basic difference is one things is about being focused on the present situation while the other is thinking about past situations or experiences.

Explanation:

Past time focus : David has good marks and he is thinking about that achievement and good grades at that time

Present time focus : David has gotten good grades right now so he is going to put in time to better himself.

Explanation:

Aristotle ladder of nature can be described as an idea (referred to as Scala Naturae) to organize all things (living and non-living) into a "ladder" where organism fits into a "step" on the ladder. He ranked animals higher than plants and plants higher than non-living things (like minerals). Humans were ranked first in his ladder.

The Great chain of Being is also a form of hierarchial ranking (of old christianity) starting from God to angels to humans to animals to plants and then finally to minerals.

These rankings have been suggested in the past by some "radicalists" to mean that all species were created from the simplest to the most complex and perfect which can be loosely translated to mean that all species were created in a fixed order, from least to most perfect

Rainbow Parrot Fish

Explanation:

Rainbow Parrot Fish is an herbivore and it is considered as competitor of corals and a direct threat to coral reef because Rainbow Parrot Fish majorly source of feed is algae which result in missing of lots of algae in corals colony. They consume most of the coral in the coral reefs with their beak like teeth therefore resulting in competition and not enough available algae source for corals. After feeding on algae , they also graze on corals in Coral reefs.

Answer:

no shape of molecules doesn't affect the chemical bond

Answer:

There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional. That is, in ionic compounds there is no intrinsically preferred direction in which a neighbour should lie for the strength of bonding to be maximized. In contrast, in a covalently bonded compound, the atoms adopt specific locations relative to one another, as in the tetrahedral arrangement of hydrogen atoms around the central carbon atom in methane, CH4, or the angular arrangement of atoms in H2O.

(A). Energy is lost when machines don't work right.

Explanation:

The false statement from the choices is that energy is lost when machines do not work right.

The law of conservation of energy states that "energy can neither be created nor destroyed , they can only be converted from one form to another. "

The only odd choice is that energy is lost when a machine doesn't work right.
