d
Mountain frogs in a lab setting with no UV ray exposure

Answers

Answer:

c

Explanation:

if the scientist was to look close there skin would be tightened up on the frog it is hard to see but if you look close you could see it

Answer:

C or D I think

Explanation:

D, you could compare frogs with no UV ray exposure to the ones with UV ray exposure

C, you can do the same but reverse

Edit: Meaning of control group is "A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results."

So its more likely to be D

Why are water striders able to "walk on water"?​

Answers

Answer:

Water striders can walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and large hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

Explanation:

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
diameter of 10 cm in the box. Susan puts 1,000 1-cm glass marbles in her box.

1. Whose box has more empty space? Explain.

Answers

Answer:

Both boxes have the same amount of empty space

Explanation:

Given

Cube Box

[tex]Length = 10cm[/tex]

Robert:

1 glass marble

[tex]Diameter = 10cm[/tex]

Susan:

1000 glass marble

[tex]Diameter = 1cm[/tex]

Required

Whose box has more empty space?

First, we need to calculate the volume of the cubic box.

[tex]Volume = Length^3[/tex]

Substitute 10cm for Length

[tex]Volume = 10^3[/tex]

[tex]Volume = 1000cm^3[/tex]

Next, calculate the volume of Robert's glass

Volume is calculated as:

[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere

Where

r = radius

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]Diameter = 10cm[/tex] --- Given

Substitute 10 for diameter

[tex]r = \frac{1}{2} * 10cm[/tex]

[tex]r = 5cm[/tex]

So:

[tex]Volume = \frac{4}{3}\pi r^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 5^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 125[/tex]

[tex]Volume = 523.8cm^3[/tex]

Next, we determine the volume of Susan's 1000 glasses

Volume is calculated as:

[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere

Where

r = radius

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]Diameter = 1cm[/tex] --- Given

Substitute 1cm for diameter

[tex]r = \frac{1}{2} * 1cm[/tex]

[tex]r = 0.5cm[/tex]

Substitute 0.5cm for radius in [tex]Volume = \frac{4}{3}\pi r^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.125[/tex]

[tex]Volume = 0.5238[/tex]

But there are 1000 glasses.

So, the volume of 1000 glasses is:

[tex]Volume = 0.5238 * 1000[/tex]

[tex]Volume = 523.8cm^3[/tex]

--------------------------------------------------------------------------------------------------------------

For Robert:

[tex]Volume = 523.8cm^3[/tex]

For Susan:

[tex]Volume = 523.8cm^3[/tex]

Since, they have the same volume.

Both boxes have the same amount of empty space

From the dimensions of glass marble for robert and susan, we can say that; none of the given boxes have more empty space.

We are told that the cubic boxes have a measure of 10 cm for its' sides.

Formula for volume of a cube is;

V = lwh

where;

l is length

w is width

h is height

Thus; V = 10 × 10 × 10

V = 1000 cm³

For Robert;

We are told that he puts a glass marble with a diameter of 10 cm in the box. The glass is usually spherical in shape and the volume of a sphere is;

V = ⁴/₃πr³

Thus;

V_rob = ⁴/₃π × (10/2)³

V_rob = 523.6 cm³

Volume left for rob = 1000 - 523.6

Volume of empty space left for rob = 476.4 cm³

For Susan;

V = ⁴/₃πr³

Thus;

V_sus = ⁴/₃π × (1/2)³ × 1000

V_sus = 523.6 cm³

Volume left for susan = 1000 - 523.6

Volume of empty space left for susan = 476.4 cm³

Answers

Answer:

D. improve fertility

Explanation:

A garden supply company has an advertisement selling beneficial bacteria. They claim that the bacteria will help gardeners grow better gardens because of better soil.

This claim is simply based on the premise or fact that some bacterias can improve fertility of the soil.

Some species of bacterias are living microorganisms that are capable of decomposing organic matter into nitrogen, carbon and other nutrients, which are then released into the soil in a plant available form when in excess and this cycle continues with reproduction of new bacterias.

Some examples of these bacterias are Klebsiella, Anabaenopsis, Beijerinckia, Azotobacter, Clostridium, Anabaena, Nostoc, Bacillus etc.

Outline THREE adaptations of terrestrial plants for their survival in their habitat.

Answers

Answer:

Stomata for gas exchange, water resistant waxy cuticles on leaves and specialized cells for support.

Explanation:

Plants have undergone several modifications for life on land. These include the development of several mechanisms:

a waxy, thick water-repellent cuticle- the thick cuticle provides a barrier to water loss from plant tissues in the leaf. stomata- these moderate the evaporation of water, an important commodity to land dwelling terrestrial organisms. They also regulate gas change cells to provide strength and rigidity- plant cells are specialized cells that contain lignin and cellulose, these are rigid provide good support against gravitational forces, Without them the stem would break and the cells would readily lose water

find the kinetic energy of a ball of mass 200 grams moving at a speed of 20m/s​

Answers

We have a mass of 200g (0.2kg) moving at 20m/s

Kinetic Energy KE = ½ mv^2 where m is mass and v is velocity

Actually, v is a vector quantity, so KE = ½ mv•v

The dot product of 2 vectors a and b is abCosθ where θ is the angle between the vectors.

Obviously v•v = v^2 Cos0 = v^2

In this case, we have KE = ½ (0.2)(20^2) = 40kg-m^2/s^2 = 40J

So we have kinetic energy in the amount of 40 Joules.

Answer is 40J...............

When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. ... Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.

Answer:

A long term change can affect how species of right now live and act.

Explanation:

Eventually, that new change would cause an evolution to occur for that species so that they can adapt and be fully prepared for the change that occur so that they can survive.
