Answer:
30 calories of energy
Explanation:
In an aquatic ecosystem, zooplanktons are primary consumer i.e. they feed on primary producers e.g phytoplanktons. They are fed on by smaller fishes e.g tilapia, which in turn is fed on by sharks. Based on this, we have a food chain as follows:
phytoplankton → zooplankton → tilapia fish → shark
From this food chain, it appears that ZOOPLANKTON is a primary consumer while SHARK is a tertiary consumer. Since only about 10% of energy is transferred to each trophic level when organisms feed on one another, if there are 3000 calories of energy available at the zooplankton, the following will be available for sharks:
For secondary consumer = 10/100 × 3000 = 300 calories for tilapia fish
For tertiary consumer = 10/100 × 300 = 30 calories for shark.

Hard structures of corals and shelled organisms are deteriorating because of
1. increasing ocean pH
2. decreasing ocean pH
3. increasing ocean temperature
4. decreasing ocean temperature
Answer:
The correct answer is - 2. decreasing ocean pH.
Explanation:
Many marine organisms such as corals that have hard calcium carbonate shells or skeletons are deteriorating due to the increase of carbon dioxide levels dissolved in marine water which leads to decreasing pH in seawater.
For example, increasing ocean acidification or decreasing pH level due to increased carbon dioxide has been shown to significantly reduce the ability to maintain their skeleton or hard structure or building again. Due to Co2 dissolving in the water means more hydrogen ions in seawater that leads to the concentration of CO3^2- ions actually decreases.

Why is mitosis necessary during the development of a human?
Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

8.Seeds- form through ____________ reproduction and contain an embryo that gives rise to a new plant. (Have adaptations that allow them to be spread by wind, water, on animals, etc.)
10.When a plant grows toward or away from a stimulus, it’s called a tropism.
a.3 Types:
i.Phototropism- a response to _________ that directs the stem to grow toward the light and roots to grow away from it
ii.Gravitropism- Stems and leaves grow away from the force of __________ while roots grow toward it.
iii.Thigmotropism- growth in response to _______. The side of the stem in contact with the object grows slower than the side not in contact. This causes the vine to twist around the object.
Explanation:
1. Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
2. Abstract
3. photo tropism I think
4. Thigmotropism describes plant growth in response to touch or contact with a solid object.

PLEASE HELP!!! URGENT, ILL GIVE YOU BRAINLIEST!!!
Using the example of the digestion of food in the human digestive system, explain why enzymes are
important for life processes.
-Explain-
NO LINKS PLEASE!!!!!
Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
question 2
Two abiotic resources that affect an ecosystem are:
A. temperature and animals
B. plants and animals
C. water and bacteria
D. soil and water
The diagram below represents some changes that took place in a bacterial population recently exposed to an antibiotic.Which statement would best explain the presence of bacteria on day 4?A) A bacterial population cannot survive exposure to antibiotics.B) This bacterial population cannot survive exposure to this antibiotic.C) Bacteria can change whenever it is necessary to survive antibiotic treatment.D) Some of the bacterial population was resistant to this antibiotic.
About the question:
You will find the diagram used to answer the question in the attached files.
Answer:
D) Some of the bacterial population was resistant to this antibiotic.
Explanation:
The term resistance refers to an inheritable change in a population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach a desired effect on the target population.
The excessive use of antibiotics on the bacteria population leads to the fixation of new mutated genes -by natural selection-. The mutated genes make these cells even more resistant to the drug.
In the exposed example we have,
Day 1 ⇒ a big population of white bacteria and only one black cell, probably carrying mutated genetic material.The population was treated with antibiotics.
Day 2 ⇒ there are fewer white bacteria and three black cells. This means that white bacteria are dying, while the black ones are reproducing.The mutated phenotype gets to survive under the effects of the chemical.
Day 3 ⇒ There are no more white bacteria. Only the black population survived and keeps reproducing.The mutated bacteria reproduce with the capability of tolerating the antibiotic dose that is usually used to destroy a population of white bacteria.
Day 4 ⇒ Black bacteria got to survive a produce a big population. Remember that bacteria follow the exponential growth model, meaning that their reproductive rate is too high. This black population survived the antibiotic action and reproduced at high rates.Fill in the blank on this paper

É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.
(English )Is it correct to say that energy follows a linear flow in the food sections, while nutrients are constantly recycled? Explain.
(Portuguese) É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.
Answer: Yes.
Responder: Sim.
Explanation: (*English) A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
(*Portuguese) Uma cadeia alimentar é uma sequência linear de organismos através dos quais nutrientes e energia passam enquanto um organismo come outro; os níveis na cadeia alimentar são produtores, consumidores primários, consumidores de nível superior e, finalmente, decompositores.
Hypothesis: If the porosity of three soils are tested, then red clay soil will have the lowest porosity.
Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.

How does evolution unify biological principles
Answer:
Evolution, which provides an explanatory framework for biological phenomena ranging from genes to ecosystems, is the single unifying theory of biology. Evolutionary science explains the unity of life by its history, whereby all species have arisen from common ancestors over the past 4 billion years.

define and give an example of conduction and convection
Answer:
Conduction: This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object.
Convection: This is a transfer of heat by mixing a fluid. Convection occurs within liquids and gases. Examples include boiling water and when warm water mixes with cold water.
