In eukaryotic cells, DNA is packaged with proteins into structures called
chromosomes. What advantage do chromosomes provide the cell?
a. They ensure equal division of genetic material when a cell divides.
b. They allow random distribution of genetic material when a cell divides.
c. They allow all genes to be expressed at the same time.
d. They eliminate the need for a nuclear membrane.

Explanation:

Answer:

Due to suitable environment of the equator.

Explanation:

Latitude is abiotic factor that has a great impact on the occurrence of fish species as we can see in the graph, the fish species increases as we go towards equator whereas decreases when we go away from the equator. This is because the climatic condition and temperature of water at the equator is suitable and warm so this suitable environment attracts more species to lives there.

Answer:

•Ingroup in biology is a group of taxa that is considered in determining evolutionary relationships. The taxa in an ingroup are closely related. In fact, they are sister groups, and they share a common ancestor. Therefore, taxa in an ingroup are descendants that split from the same node in the cladogram.

Answer:

Uncontrollable cell division.

Explanation:

Cancer is a disease which is caused when cells division is uncontrollable and spread into surrounding cells and tissues. Mutations in genes is also responsible for the cause of cancer because this mutation accelerate the rate of cell division or inhibiting normal controls on the system, such as programmed cell death. When the mass of cancerous cells grows with the passage of time, it turn into a tumor.

Answer:

Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.

Answer:  Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.

Answer:

Natural selection gives organisms what they need

Explanation:

The species constantly evolve because of the changes around them. Natural selection gives organisms what they NEED in order to survive. "Natural selection produces organisms perfectly suited to their environments".

Species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.

It is the process through which populations of living organisms adapt and change where individuals in a population are inherently variable, meaning they all differ in some way. This variation means that some individuals have better adaptations to the environment than others.

Thus, species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

Answer:

predators

Explanation:

The correct answer is predators. An alien species that finds plenty of food and suitable habitat in its new home is usually able to find mates and reproduce well. But the competing species may become endangered or even extinct, because the alien (now invasive) species has no natural predators in the new environment, and its population can therefore grow without limits.

Answer: predators

Explanation:

Answer:

2/8

Explanation:

I did this before

1/8 or 12.5% is the probability of getting dwarf plants with red flowers in the F1 progeny.

Dihybrid is defined as the cross observed between two characters, in which two different gene is responsible for the two particular characters.

In the given question plant height and flower color are observed. A tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr).

Gametes: TtRr - TR, Tr, tR, and tr

                 Ttrr - Tr, Tr, tr, and Tr

Genotypes: Tall, Red (T_R_) = 6

                   Tall, white (T_rr) = 6

                   Dwarf, red (ttR_) = 2

                   Dwarf, white (ttrr) = 2

Therefore, the probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

Answer:

This is the Prophase. Mitotic Prophase,

Explanation:

The process  cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called  a multiplication division because two daughter cells are  form from a single  the mother cells. Each of the daughter cells can also undergo Futher divisions.

It is the second stage fist  mitotic cells division after the first phase called Interphase.

In this stage, the nuclear membrane disappear, nucleolus disintegrate and  the nucleus disappeared  This is followed  by the constriction of the chromosome to sister chromatids.

The constricted nuclear membrane leads to the releases of the chromatids This is  followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.

other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)

False

False because reflexes and snap reactions are generally bounced back directly from the spinal cord to save time. An example could be touching something hot because you react and move away instantly rather than your body burning for a second while the brain processes the information.
