Overfishing decreases the population of trout living in a river.
What would also decline because of the decreasing number of trout?
A mayflies that are part of the trout's diet
B. eels that compete with the trout for food
C. birds that use the trout as a source of food
D. fish that lay eggs that are eaten by the trout
Answer:
C. birds that use the trout as a source of food
Explanation:
Living organisms feed on one another in their natural environment in order to obtain energy for their various activities. According to this question, overfishing by humans decreases the population of trout living in a particular river.
This means that in that aquatic ecosystem (river), the population of organisms that feed on trout as a source of energy will also decrease. In this case, it is the birds. Hence, birds that use the trout as a source of food.
Answer:C
Explanation:
Because birds use that as a source of food.

A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
O lunar eclipse
O summer solstice
O solar eclipse
Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.

Within one minute, 5% of the substrate had reacted. a) What percentage of substrate will have reacted in 5 min? b) If the initial concentration of substrate was 8x10-7 M, what percentage of substrate will have reacted in 5 min? c) Calculate Vmax. d) A concentration of 9x10-7 M, how long will it take for 50% of the substrate to react? e) A 10-6 M concentration, how long will it take for 75% of the substrate to react?
Answer:
[S] = 0.02 , Km = 1.2 x10^ -4 , rate = dP/dT = product formed per time = 2.7 x 10^ -6 moles /30 = 9 x10^ -8 we know rate = vmas

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.
