Urchin population has dramatically increased during the past 20–30 years.  The trend between 20 and 30 years shows a sharp rise in the urchin population.

Sea urchin growth rate and gonad size declined with increasing time after kelp bed loss, although populations increased as a result of strong recruitment rates in the first two years following kelp bed destruction.

Due to rising waters that caused a sickness that killed the purple sea urchin's natural predator, the starfish, the number of purple sea urchins on the north shore has multiplied. The urchins have now destroyed the kelp beds where abalone formerly thrived.

Stony corals are the most important reef builders, but organ pipe corals, precious red corals, and blue corals also have stony skeletons.

There are also corals that use more flexible matter or tiny stiff rods to construct their skeletons—the sea fans and sea rods, the buoyant soft corals, and the black corals. Coral reefs protect the seaboard from storms and erosion, provide jobs for local groups, and offer opportunities for pleasure. They became the planet's very first reef-builders and are index fossils for take-out Lower Cambrian rocks worldwide.

Coral reefs are built by coral polyps as they produce layers of calcium carbonate below their bodies. The corals that build reefs are known as “hard” or “reef-building” corals.

Whatever the situation, having mushrooms pop up in your lawn can be a nuisance, an eyesore and, if you have children, potentially dangerous. Learn why mushrooms appear and what you can do about them.

What are mushrooms?

Mushrooms are actually part of a fungus that grows underground, hidden from sight. The mushroom is the tip of a fungus iceberg, if you will – a clue that a large fungus lies buried in soil. Lawn fungi and their mushrooms do not harm a lawn. Mushrooms growing in grass are actually good guys in the ecosystem of your yard, breaking down organic material into nutrients your lawn can use.

A mushroom reproduces through spores, similar to seeds. The mushroom releases the spores, which spread by wind or water, to start a new fungal colony.

When most people hear the word "mushroom," they think of the typical umbrella-shaped one, which is sometimes called a toadstool. But you might also spot other types of lawn fungus, including puffball, shaggy mane, Japanese parasol or the oddly-shaped and smelly stinkhorn.

Overgrazing is not a practice of the Green Revolution while irrigation ,mechanization and pesticide use are practices of green revolution.

Answer:

A full term pregnancy begins with the woman’s last menstrual period and lasts for around 40 weeks. There are 3 stages of pregnancy which are the first, second, and third trimesters. Each trimester of pregnancy lasts between 12-14 weeks and 3 stages of fetal development. There are three stages of fetal development: germinal, embryonic and fetal during the 1st trimester of pregnancy.

The germinal stage begins at conception when the sperm meets the egg in the fallopian tube and is the shortest stage of fetal development. The sperm fertilizes the egg and creates a zygote. The zygote takes a week to travel to the uterus where it  begins cell division. Cell division happens many, many times until it becomes a blastocyst. The blastocyst reaches the uterus and attaches itself to the lining of the uterus. Once the blastocyst is successful in implantation, the body then creates hormones to support the pregnancy and to stop the menstrual cycle.

The embryonic stage begins in the  third through the eighth week of pregnancy, The blastocyst begins to take on human characteristics and is now called an embryo. During the embryonic stage, the embryo develops little buds that will become the legs and arms, structure, and organs. The embryo’s heart begins to develop and pulse during this stage. The embryo’s organs and systems have taken shape by the end of the embryonic stage.

The fetal stage is where the embryo becomes a fetus and lasts from the 9th week of pregnancy until birth. Around the 9th week, a sex is assigned to the fetus but can’t be detected yet until around the 19th–20th week of pregnancy.  During the 2nd and 3rd trimester, the fetus’ systems and organs continue to grow and the majority of growth, both in length and weight, happens.

Circle: The Effect of Temperature on the Solubility of Salts. Description: The table shows the solubility of different salts in water at various temperatures.

What do you mean by Temperature?

In biology, temperature is the measure of the average kinetic energy of the particles that make up a substance. Temperature is an important factor that can affect the rate of chemical reactions, the movement of molecules, and the behavior of living organisms. Temperature also plays a role in the survival of organisms, as certain temperatures outside of their normal range can be lethal.

When a salt is added to water, the temperature of the solution will affect the amount of the salt that dissolves. At higher temperatures, the solubility of the salt increases and more of the salt will dissolve. At lower temperatures, the solubility of the salt decreases and less of the salt will dissolve. This is due to the fact that heat energy increases the motion of particles and allows them to come into contact with each other, which increases the likelihood of a reaction occurring. As the temperature increases, the number of particles that can react with each other in a solution increases, leading to an increased solubility.

For the first six years, the deer population on Wallah Wallah Island increases dramatically before stabilizing.

Natural fluctuations in white-tailed deer numbers occur throughout the year. Birth rates for deer rise, as do numbers when other animals enter the region (immigration). Deer populations decline as a result of fatalities, animal emigration, or dispersal (emigration). Births plus immigration minus deaths plus emigration equals population change.

Deer populations, like those of the majority of other species, follow a predictable pattern of growth after the breeding season and drop after the hunting season and winter mortality. Over the course of a year, a population's deer numbers change.

The peak deer population is during late spring and early summer when fawns are born. The deer population is slightly decreased throughout the summer by fawn predation. In the fall, hunters kill extra animals to lower the population. Due to some deer passing away from sickness, malnutrition, and predator attacks, mid-late winter is when the population is at its lowest.

Deer populations' capacity to successfully reproduce and sustain a stable population throughout time is influenced by a variety of factors. Disease, predator-prey interactions, habitat erosion and degradation, food availability, hunting pressure, and meteorological conditions are a few of these. Deer populations are dynamic and constantly alter due to a variety of circumstances.

Deer populations are constrained from procreating at a rate that exceeds what their environment can support. Population levels may decrease if limiting forces are present in excess.

Deer require food, drink, shelter/cover, and room to move around and locate their daily needs in order to thrive. These are the crucial elements that make up a habitat. They are essential to deer's ability to survive and procreate.

Because they are herbivores, deer eat only vegetation. The majority of the water that deer require comes from the plants they consume. A deer needs shelter and cover to survive for a variety of reasons, including protecting young fawns from predators, avoiding bad weather, and evading hunters.

Option B: homozygous recessive females and hemizygous recessive males would express a trait which is X-linked recessive.

Homozygous recessive females and hemizygous recessive males for a dominant allele express an X-linked recessive trait more significantly. This also implies that females exhibit the trait more frequently. This is because females have two X chromosomes, whiles males have only one. If a female is heterozygous for a particular trait, it would be suppressed by the non-carrier allele and would not be expressed. Hence, females with homozygous recessive trait would be expressive. Option B is thus the right choice.

X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be always expressed in males (who must be homozygous for the gene mutation because they have one X and one Y chromosome) and females. Carriers are females who have one copy of the mutated gene.

For a dominant allele, homozygous recessive females and hemizygous recessive males exhibit an X-linked recessive characteristic more prominently. This also means that females are more likely to display the feature.

This is due to the fact that females have two X chromosomes whereas males only have one. If a female is heterozygous for a certain characteristic, the non-carrier allele suppresses it and it is not manifested. Females with a homozygous recessive trait would so be expressive. Option B is consequently the best option.
