Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?

Answers

Answer:

The question lacks options, the options are:

A. The green trait is the dominant trait.

B. The offspring will inherit one gene from each parent.

C. The offspring will have both green and yellow seeds.

D. Each offspring will have a unique set of alleles.

The answer is optionB

Explanation:

This question describes a monohybrid cross i.e. involving a single gene coding for seed colour in pea plant. One allele codes for green seeds and the other for yellow seeds.

Based on the question, a plant that has the same alleles for yellow seeds is crossed with another plant that has same alleles for green seeds. The offsprings produced will have two different alleles i.e. heterozygous, contributed by each parent.

Hence, the offsprings will inherit one form of the gene from each parent.

Answer:

THE ANSWER IS B!!!

Calculate if 1000 units of energy are available at the producer level of the energy pyramid about how many units are available for first level consumers? Second level consumers? Third level of consumers?

Answers

Answer:

first level consumers?- abou 100 units

Second level consumers- about 10 units

Third level of consumers- about 1 unit

Explanation:

Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.

A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.

However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.

Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.

Explanation:

i got a 100 on the Quiz "Earthquakes"

The strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.

What is an Earthquake?

An earthquake may be defined as an activity that involves the unanticipated and brutal shaking of the ground, generally causing huge destruction, as an outcome of movements within the earth's crust or volcanic action.

Geologists utilize an instrument that is known as a seismograph that measures the strength of an earthquake. With the help of this instrument, they find the center of an earthquake on the basis of the highest strength.

Therefore, the strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.

In DNA replication, enzymes play a major role.

Enzymes identify the starting point of replication, attach itself and then unwind the Deoxyribonucleotide acid DNA Strand to form the replication fork.

Enzyme Helicase unwind and breaks the hydrogen bond between the base pair, opening up the helix structure to form a template for the new strand.

DNA polymerase also play a major role, it synthesis new DNA by adding primer to the DNA sequence for replication to occur, they also proof read the copy of DNA Strand being made to avoid errors during replication and add nucleotide to the growing DNA strand.
