Which of the following characteristics do homologous chromosomes exhibit?.

Answers

Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.

Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.

Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.

what evidence can be cited from the fossils to reconstruct climate change over time?

Answers

Answer: When studying the museum’s collection of plant fossils for information about the climate, Wing and Barclay start with plant leaves.

Roughly 56 million years ago, during a time called the Paleocene Eocene Thermal Maximum (PETM), Earth’s average temperature rose four to eight degrees Celsius in less than 10,000 years. The cause was geologic processes releasing trillions of tons of carbon dioxide into the atmosphere. The dramatic shift in global climate forced massive upheaval in ecosystems around the world.

“It’s the best analogue for the climate change we’re experiencing today,” Barclay said.

Fossil plants and their leaves from the PETM show that ecosystems shifted massively because of the rapid increase in global temperature. But global warming during the PETM did not come from humans. So, scientists today are working on ways to extrapolate information from that period and apply it to the even faster and more drastic events of today.

What will most likely happen if a sound wave moves from the air through a solid?

It will increase in frequency.
It will decrease in speed.
It will increase in speed.
It will decrease in wavelength.

Answers

Answer:

Explanation:

It will increase in speed.

Hopes this helps you.

The speed of sound waves will increase from air through a solid.

What is effect of medium on wave speed?

The speed of a wave increases with increase in density of a medium.

Sound waves travel fastest in solids and slowest on gases.

Therefore, the speed of sound will increase on moving from air to a solid.

The answer is chloroplasts

1. **Menstrual Cycle**: The menstrual cycle is the regular hormonal cycle that occurs in women of reproductive age. It typically lasts around 28 days, although the length can vary from woman to woman. The cycle is divided into different phases, with ovulation occurring during one specific phase.

2. **Follicular Phase**: The menstrual cycle begins with the follicular phase, where hormones, primarily follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are released by the pituitary gland. These hormones stimulate the growth and maturation of follicles in the ovaries.

3. **Ovarian Follicles**: Within the ovaries, multiple tiny sacs called ovarian follicles contain immature eggs. Each month, one of these follicles becomes dominant and continues to grow while others degenerate.

4. **Mature Follicle Development**: As the dominant follicle grows, it secretes estrogen, a hormone that prepares the uterus for a potential pregnancy. The rising estrogen levels also trigger a surge in luteinizing hormone (LH) around the middle of the menstrual cycle.

5. **Ovulation**: The LH surge triggers the final stage of ovulation. It causes the mature follicle to rupture and release the mature egg from the ovary. The egg is swept into the fallopian tube by tiny hair-like structures called cilia.

6. **Fertilization**: The released egg remains viable for about 12-24 hours. If sexual intercourse occurs during this time and sperm are present in the fallopian tube, fertilization may occur. Fertilization is the process where the sperm penetrates the egg, resulting in the formation of a zygote (fertilized egg).

7. **Implantation or Menstruation**: If the egg is not fertilized, it will eventually disintegrate, and hormone levels will drop. This leads to the shedding of the uterine lining, causing menstruation to occur. On the other hand, if fertilization occurs, the resulting zygote will undergo several divisions and travel down the fallopian tube to the uterus, where it may implant into the uterine lining and develop into a pregnancy.

Ovulation is a crucial event in the female reproductive cycle, marking the release of a potential egg for fertilization. It is a key factor in determining fertility and the ability to conceive a child.

Answers

In this case, researchers observed a trade-off between the ability to tolerate harsh dry conditions and the ability to colonize deeper water. This type of trade-off can increase the fitness of only one phenotypic trait.

An evolutionary trade-off can be defined as an evolutionary mechanism where a trait can increase its adaptive fitness in the detriment of decreased adaptive fitness in another phenotypic trait.

In trade-offs, the evolutionary adaptive processes cannot optimize a given trait without compromising another.

A well-known example of an evolutionary trade-off is the balance between the number of eggs that a bird can produce in a determined clutch.
