Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?

Answers

Answer:

The bird population might have to migrate in search for food or may decline in numbers.

Explanation:

This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.

What is one difference between primary and secondary succession? Primary succession can start from bare rock; secondary succession starts from organic soils. Primary succession occurs in habitats with rich organic soil; secondary succession does not. Primary succession is always caused by human disturbances; secondary succession is not. Trees are often the first colonizing species in primary succession, but trees are never the first species in secondary succession.

Answers

Answer:

Primary succession can start from bare rock; secondary succession starts from organic soils.

Explanation:

Primary succession is when the growth of pioneer species rake place in an bare and new environment. The secondary succession is when the growth of species take place due to the disturbances in the primary succession. The secondary succession is based on fire, floods, or any man-made disturbances in the region.

What are sporophytes and gametophytes?

Answers

Answer:

A. Two different forms a plant can have

Explanation:

Higher plants, lower plants (mosses) and ferns undergo a life cycle called ALTERNATION OF GENERATIONS. In this life cycle, they switch between a haplontic and diplontic forms of life.

The haplontic (haploid) life form which produces haploid (n) gametes is called GAMETOPHYTE while the diplontic (diploid) life form which produces the spores that germinates is called SPOROPHYTE. Hence, sporophyte and gametophyte are two different forms a plant can have.

Magnetic fields on the sun are produced by the sun’s uneven rotation and:
A. The movement of sunspots on the sun’s surface.
B. The movement of gases in the corona.
C. Gases in the convective zone.
D. Gases in the radiation zone.

Answers

Answer:

The correct answer is - C. Gases in the convective zone.

Explanation:

The heat of the sun causes the atoms to be ionized and create a charged gas known as plasma. These gases or plasma are move in the convective zone with the uneven and rapid rotation of the sun.

This creates the electric currents due to the charge in gases which ultimately create magnetic fields. Sun's rotation causes the sun's overall magnetic field to have some degree of order and to be somewhat stable over time.

Answers

Answer:

warm: gentle long lasting rain , half red circles, slides over the top of air masses

cool: blue triangles, force existing air into atmo., heavy storms

Explanation:

Gentle, long-lasting rain, sliding over the top of existing air mass and shown as red half circles on the map was an indicator of warm fronts whereas heavy storms, forcing existing air up into the atmosphere and shown as blue triangles on the map are indicators of cold fronts.

What are warm fronts?

A warm front occurs when warm air mass overtakes colder air mass while moving forward resulting in the production of precipitation, clouds, or thunderstorms. A light rain or drizzle is also a result of warm fronts.

A cold front occurs when a cold air mass undercuts a warm air mass while moving forward. when the warm air is lifted by colder air, it causes clouds to condense resulting in thunderstorms, or even tornadoes. Severe weather accompanied by strong winds and low temperatures was created by cold fronts.

Warm fronts bring gentle, long-lasting rains, slide over the top of the existing air mass, and are shown as red half circles on the map whereas cold fronts bring heavy storms, forcing existing air up into the atmosphere, and shown as blue triangles on the map.

Therefore, warm fronts bring gentle and long-lasting rains, whereas cold fronts bring heavy storms.

Answers

Between DNA and RNA goes Transcription. Between RNA and Protein goes Translation.

There are two main process involved in producing a protein molecule from the information in DNA, the process of formation of RNA from DNA is transcription and from RNA to protein is translation.

In molecular biology, transcription and translation play crucial roles in protein synthesis. On the basis of a DNA template, a complementary RNA molecule is created during transcription.

The DNA strand is unravelled during transcription, and an RNA polymerase enzyme uses complementary base pairing to create an RNA molecule.

The messenger RNA (mRNA), a newly formed RNA molecule, transports the genetic information from the DNA to the ribosomes.

On the other hand, translation takes place at the ribosomes and entails converting the mRNA sequence into an amino acid sequence. Specific amino acids are delivered to the ribosomes by transfer RNA (tRNA) molecules, where their anticodons are matched with the complementary codons on the mRNA.

Until the ribosome reaches a stop codon, which indicates the completion of protein synthesis, this process continues.

Thus, the first process is transcription and the second is translation.
