Answer:

Cause and effect

Explanation:

In cause and effect relationship the cause is responsible to produce an effect, therefore, a cause can be considered as producer and effect is the consequence of the cause. A person, event, situation or object can be a cause and result of their action said to be their effect.

Therefore in this situation, the cause is invasive species of China and Europe and the effect is the extinction of the native species and American chestnut tree by these invasive species.  

Therefore cause and effect is the term that best describes the structure of the passage.

Substances intended for tubular reabsorption travel from the filtrate of the proximal convoluted tubule next to the ________.

2.Which of the following represents a genetic cross between 2 individuals that are each heterozygous for both traits?
wariber [46]

Answer:

A. AaBb x AaBb

Explanation:

The term heterozygous refers to the presence of two different alleles of same gene in an organism. The one allele can be of wild type (original type) and one can be mutated or newly formed.

In the question, two traits are represented by two letters, A and B and alleles as A and a and B and b, respectively. We are asked about a cross involving two traits and two individuals in such a way that both are heterozygous.

If we look at option A, AaBb x AaBb,

we see that one trait A and the other trait B is in heterozygous form (Aa and Bb) in both individuals.

If we look at option B. AABB x AABB

we see that one trait A and the other trait B is in homozygous form form (AA and BB) in both individuals. Homozygous means when the alleles are same for each trait in an individual.

If we look at option C,Aa x Bb

There are not two traits, one trait of one individual and other trait of other individual is being crossed that is not possible.

If we look at option D. AAaa x BBbb

Again, the individuals are homozygous for two traits.


Therefore, A is best option.


Hope it helps!

Alex17521 [72]
Correct answer - A (Elephants have few offspring, so they need to protect them from predators.)

Why? - The herd is led by the oldest and often largest female in the herd, called a matriarch. They live in herds so that the young elephants stay safe from predators.

Organisms can be classified in the same species by morphology and
snow_lady [41]
I believe the correct answer would be <span>variation. The definition of variation in biology means,</span><span> any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials. So i think that organisms can also be classified as variation. Hope this helped. ♥ ☺

Which describes a climate effect on the rate of weathering?
tester [92]

Answer:

Cold climates favor mechanical weathering.

Explanation:

A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering
