Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era. (See the geologic time scale.) The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.


A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.


Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question.


Part B - Whats the students scientific question?

Part C - Construct at least two possible hypotheses for the students experiment

Part D - Choose one hypotheses to make a prediction

Part E - How would you conduct your investigation? In your answer, explain your independent and dependent variables.

Part F - How does the design of your experiment control for outside factors that may affect the results?

Part G - How do you plan to analyze and communicate your results?

B- Do tomato plants grow faster and taller using natural compost or artificial fertilizer?

C- 1: Tomato plants grow faster in compost than in fertilizer. 2: Tomato plants grow taller in compost than in fertilizer.

D- Tomato plants grow taller in natural compost rather than artificial fertilizer.

E- First, I would plant three tomato plants in different pots. One would be full of natural compost, one full of artificial fertilizer, and one with regular dirt. Then, I would wait a few months, giving them the same amount of water each day, and record the results. The independent variables are the amount of time and water, while the dependent variable is the height of the plant after a few months.

F- My design includes a control group, being the plant with the plain dirt, as well as minimizing error by treating the plants with the same amount of water.

G- After a few months, I would record the height of all three plants and see if the tomato plants grown in natural compost or artificial fertilizer were taller.

which disease is caused when there isn't enough bile to breakdown fat and oil in food . And how is it caused​

Answers

Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.

Phytohormones are responsible for the movement of plant towards stimulus. Auxin is the main phytohormone responsible for gravitropism and phototropism of plants.

What is Plant Movement?

Plants are immobile however different parts of the plant show movements in response to the stimulus in the environment. The chemicals present in the plant body which are responsible for these movements are called phytohormones or plant hormones.

Auxins are the main hormones responsible for the cell elongation in plants.  Auxins are responsible for the phototropism (movement of plant parts in response to light) and gravitropism (movement in plants in response to gravity).

Roots of a plant grow downward and exhibit positive gravitropism whereas stems on the other hand, exhibit negative gravitropism since they grow upwards and against the gravity. If you place a plant on its side or even upside down, the stem will curve its way up in response to gravity and auxin is responsible for this movement.

What is the difference between weathering and erosion? (Site 1).

Answers

Answer:

Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.

Explanation:

Because for answer A, only eukaryotes have DNA, also for B, only eukaryotes have a nucleus and lastly, for D, only eukaryotes contain membrane-bound organelles. hope this helps :)

Both cell types undergo cell division by mitosis. Therefore, option (C) is correct.

What are eukaryotic and prokaryotic cells?

A nucleus and other membrane-bound organelles are exclusively found in eukaryotic cells, which is the main distinction between prokaryotic and eukaryotic cells. Prokaryotes and eukaryotes, respectively, are made up of prokaryotic and eukaryotic cells. Eukaryotes often have several cells, but prokaryotes are invariably unicellular. Eukaryotic cells are also between 100 to 10,000 times bigger and more complicated than prokaryotic cells.

Prokaryotic DNA is kept in the cytoplasm, while DNA in eukaryotes is kept in the nucleus. Additionally, double-stranded chromosomes that are compressed by histones are where eukaryotic cells store their DNA. Prokaryotic organisms, on the other hand, only contain one basic circular chromosome and a variety of plasmids, which are tiny DNA rings. In comparison to prokaryotic cells, the DNA of eukaryotic cells contains a higher percentage of non-coding DNA and proportionately less coding DNA.

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.

Answers

Ernest would be swimming at 3.25 units on week 10

The explicit formula is given as:

[tex]a_n = a_1 + (n - 1) \times d[/tex]

Also, we have the following parameters

[tex]a_1 =1.0[/tex] -- the initial distance

[tex]d =0.25[/tex] --- the difference between concurrent distances

In week 10, the value of n is 10.

Next, substitute 10 for n in the explicit formula [tex]a_n = a_1 + (n - 1) \times d[/tex]

So, we have:

[tex]a_{10} = 1.0 + (10 - 1) \times 0.25[/tex]

Subtract 1 from 10

[tex]a_{10} = 1.0 + 9 \times 0.25[/tex]

Multiply 9 by 0.25

[tex]a_{10} = 1.0 + 2.25[/tex]

Add 1.0 and 2.25

[tex]a_{10} = 3.25[/tex]

Hence, Ernest would be swimming at 3.25 units on week 10

Which statement best explains why the population stabilized and why?!

A population of chipmunks migrated to an environment
where they had little competition, Their population quickly
increased but eventually stabilized as shown in the graph.

A. Interbreeding between members of the population increased the mutation rate.

B. A predator species came to the area and occupied the same niche as the
chipmunks

C.
The population size became limited due to factors such as availability of food.

D. An increase in the chipmunk population caused an increase in the producer
population.

Answers

Answer: C. The population size became limited due to factors such as availability of food.

Explanation:

Out of all the choices, C is the most likely to happen since more often then not, food runs out because a species has too many members. C is an example of the environment’s carrying capacity limiting the chipmunk species.

Since we are not told if the chipmunk population is really small, interbreeding may not happen. Predators hunt prey, not eat fruits like chipmunks do (I’m assuming what chipmunks eat.) If there was a predator species that came in, they would hunt the chipmunks instead of competing for the same resources. D just doesn’t make much sense in my opinion because that wouldn’t limit the chipmunk population.

The population size became limited due to factors such as availability of food in the chipmunks. Thus the correct option is C.

Why the population size become limited?

The population size become limited because of carrying capacity. It can be defined as a species' average population size in a particular habitat.

The chipmunks species population size is limited by environmental factors like adequate food, water, shelter, and mates. If these needs are not met, the population will decrease until the resource resile.
