PlLEASE HELP ME> I NEED THIS ANSWER RIGHT NOW. The bass and crayfish likely “died off” because the rapid growth of the algae eventually caused the level of dissolved oxygen to decline to a point that these oxygen-dependent organisms could no longer survive. How would you modify this investigation of the pond organisms to determine if the algal bloom really was the cause of the bass and crayfish die-offs?

Answers

Answer 1

Answer:

bacteria blooms and decreased underwater photosynthesis causes hypoxia, killing the fish. c. floating algae die, increasing sunlight penetration and heating the water. ... This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water

All of the following are used by taxonomists to create evolutionary links between species EXCEPT
Select one:
a. analogous structures
b. the fossil record
c. molecular data
d. vestigial structures

Answers

A Analogous structures

The fossil record, molecular data and vestigial structure would help taxonomists to create evolutionary links between species except analogous structures.

What do you mean by fossil record?"A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order."What is molecular data?"Molecules such as sequence of DNA used in studies of intra-specific variation and studies of similarity among species."What is vestigial structure?"Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures."What do you mean by taxonomists?"Taxonomists are professionals who specialize in classifying and sorting information based on similar characteristics and patterns."What are analogous structures?The structure of different species performing similar function but are from different origin (do not have common ancestor).

The fossil record, molecular data and vestigial structure all would help taxonomists to find evolutionary links between species where through  analogous structures no links would be created.

Hence, the correct option is a. analogous structures.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.

Answers

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.

Explanation:

The following that is not a health risk associated with ozone is obesity. The correct option is C.

What is ozone?

Ozone is a trioxygen inorganic molecule that is of pale blue color. The ozone layer is present in the stratosphere of the atmosphere. It absorbs the UV rays coming from the sun. Thus, it is a protective layer that saves from UV rays.

UV rays are harmful rays that affect health. It creates skin problems and many other health problems. So the ozone layer protects us from UC radiation, it acts as a shield.

Obesity is a condition in which the body becomes fat. It happens with the accumulation of fat in the body. This does not occur with UV rays. It occurs due to food. So this will not be a health risk associated with ozone.

Thus, the correct option is C.  obesity.

Answers

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

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.

Answers

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.
