How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.

Answers

Answer:

Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.

Explanation:

Speciation is an ecological and biological process through which new species are formed due to isolation.

In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).

As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.

What happens during interphase? (Check all that apply)
A. General Cell Processes

B. Growth

C. DNA Replication

D. Mitosis

Answers

Answer:

A. General Cell Processes

B. Growth

C. DNA Replication

Explanation:

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. So, the option A, B and C are correct.

What do you mean by interphase?

Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? (1 point) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans, O All these organisms require oxygen to survive. O The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. O Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.​

Answers

Answer:

The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,

Explanation:

It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.

Answer:

(Q1) Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.

(Answer)They are vestigial structures that once performed an important function for human ancestors.

(Q2) Which statement is true?

(Answer) Imprints of leaves or footprints in sedimentary rock are fossils.

(Q3) Which statement about these fossils is supported by the evidence in the diagram?

(Answer) Homo erectus is the most recent ancestor to modern humans.

(Q4) Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?

(Answer) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.

(Q5) Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals. Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?

(Answer) a close evolutionary connection between humans and many other mammals

How do mutations and the genetic
reshuffling that occurs during sexual reproduction benefit an organism? Select one:
They reduce the chances the organism will develop lethal diseases.
They cause loss of useless traits from the entire population.
They can make the organism better suited to the environment
They prevent the offspring from becoming prey for predators.​

Answers

Answer:

they can make the organism better suited to the environment.

Explanation:

often when an organisms environment changes, the organism will change with it in order to survive...it's the survival of the fittest theory...you either adapt to your changing environment or the species will die off. this is shown in the way that different species of birds have differently shaped beaks based on the types of seeds and flowers available for them to eat. some eat big seeds and some eat small ones ...the humming bird has a certain flower it collects nectar from as food....when the flower gets larger, making the near further down and harder to reach, the humming birds beak will become slightly longer over a few generations making the better equipped to reach the nectar again ....

As part of legislation enacted for the stated purpose of improving science skills of schoolchildren, Congress appropriated funds to permit public school teachers who had been certified by state school districts as science lab instructors to provide supplemental science instruction to any students in either public or private schools who did not have access to science lab resources. To help ensure content neutrality, the statute required the instructors coming to the private schools to use portable science labs supplied by the public school districts, which contained the equipment and experiments that the instructors used for the same purpose in the public schools. A citizens' group filed suit in federal district court to challenge the constitutionality of funding the science teachers for private schools, alleging that most of the private schools covered by the statute were religiously affiliated schools.
