Draw diagrams to highlight the explanation.
a. Mangrove
b. Coral reef.​

Answers

Answer 1

Mangroves serve as a vital nursery habitat for many marine species, including fish, crustaceans, and mollusks. Coral reefs are incredibly important for sustaining marine biodiversity, as they provide habitat for approximately 25% of all marine species.

a. Mangrove ecosystems are found in tropical and subtropical coastal areas and consist of mangrove trees, which are specially adapted to live in saltwater environments. Mangroves serve as a vital nursery habitat for many marine species, including fish, crustaceans, and mollusks.

The root systems of mangroves provide shelter for juvenile fish and other organisms, while the leaves and branches provide a source of nutrients for other marine life. Mangrove forests also help to stabilize coastlines and protect them from erosion by reducing the impact of waves and storms. Additionally, mangroves play an important role in carbon storage and help to mitigate the effects of climate change.

b. Coral reefs are underwater ecosystems composed of coral polyps, algae, and a diverse array of other marine organisms. Coral reefs are incredibly important for sustaining marine biodiversity, as they provide habitat for approximately 25% of all marine species.

The coral polyps themselves serve as the foundation of the reef structure, while algae and other marine life provide a source of food for many reef-dwelling organisms.

Additionally, coral reefs help to protect coastlines from storms and erosion by absorbing the impact of waves. Unfortunately, coral reefs are under threat from climate change, overfishing, pollution, and other human activities.

Testes: The testes are responsible for the production of the testosterone in males.

Ovaries: Ovaries are responsible for producing eggs for fertilization and they also produce hormones such as estrogen and progesterone.

Vas deferens: It helps in the transportation of mature sperm to the urethra in preparation for ejaculation.

Semen: It contains sperm cells that helps in the fertilization of female eggs.

Uterus: It helps in the nourishing and housing the fertilized eggs until the offspring is ready to be delivered.

Seminal vesicle: The function is to produce and store fluid which will eventually become the semen.

Epididymis: It carries and store the sperm cells that are created in the testes.

Explain how you would use the number line to solve the following equation. You can write out the fraction names or use the forward slash (/) on your keyboard to represent the fraction bars.

four and two eighths minus two and five eighths equals

a number line from zero to three with a tick on every eighth

subject: science

Answers

Answer:

55/8 as a mixed fraction

Explanation:

4 2/8 - 2 5/8 = ?

Four and two-eighths can be represented as a mixed number by multiplying (4x8+2)/8 = 34/8

Two and five-eighths can be represented as a mixed number by multiplying (2x8+5)/8 = 21/8

Then, these two values can be easily added. 34+21 = 55/8

You can plot this on a number line by also representing these mixed fractions as a decimal, and then adding them - you can draw lines to represent the addition process.

Since the number line already represents a tick on every eighth (which is the fraction you would primarily be using), this will make it earlier.

Individuals with mental illness are often mistreated in jail because mental illness is misunderstood.
Individuals with mental illness should be treated the same as those with physical illness or no illness.
Individuals with mental illness can be isolated away from the public in jail.

Answers

Answer: Individuals with mental illness are often mistreated in jail because mental illness is misunderstood.

Explanation:

There are specialized hospitals made for the treatment of mental illnesses just like there are for physical illnesses. So, people with mental illnesses should be moved to specialized hospitals as they also need to be treated.

What is the purpose of psychiatric hospitals?

Psychiatric hospitals are made to provide the proper treatment and care required by the people suffering from various forms of mental illnesses. These hospitals are equipped with doctors with specializations in psychiatric health, also called psychiatrists and other staff who are trained to care for the patients.

When people suffering from a mental health issue commit a crime or break the law, they should not be kept in prison as neither they nor other inmates would be safe in such a condition.

If a person suffering from a mental illness needs to be imprisoned, they should be relocated to a specialized psychiatric hospital as they would require proper treatment for their issues and would not face challenges due to other patients and staff at the hospital as they would if they were kept in jail.

What kind of geological forces or events cause mountains to form? Using the Himalayan Mountains as an example, explain the process of mountain building that is caused by plate movement.

Answers

The Indian Plate and Eurasian Plate colliding caused the formation of the Himalayan Mountains and Tibetan Plateau.

When India and Tibet collided, the relatively light sedimentary and metamorphic rock that makes up the Indian subcontinent pushed against Tibet, driving it upwards, and creating a gigantic mountain fold instead of descending with the plate.

Where continental plates clash, mountains form. Each plate will not sag below the other because they are the same thickness and weight.

Instead, they give way and fold until the rocks are forced to take the shape of a mountain range. Mountains keep rising in height as the plates continue to collide.

As a result of the Indian Plate and Eurasian Plate colliding, the Himalayan Mountains and Tibetan Plateau were created.

As a consequence of infection by a temperate bacteriophage such as lambda, the host cell:.

Answers

The host cell may lyse or may continue to divide and replicate both itself and the prophage.

What is the effect of temperate bacteriophage on a host cell?

Lytic cycle:

The infecting phage kills the host cell at the end of the lytic cycle, also known as a virulent infection, to create a large number of its own offspring. The phage genome immediately produces early proteins that degrade the host DNA after being injected into the host cell, enabling the phage to take over the cellular machinery.

The remaining proteins needed to construct fresh phage particles are subsequently synthesized by the phage using the host cell. The new genetic material is packed into the head while new daughter phage particles are built, and the heads and sheaths are created independently. In the course of this process, phage enzymes gradually weaken the host cells, which eventually burst, dispersing 100–200 additional phage progeny into the environment.

Lysogenic cycle:

The lysogenic cycle, also known as temperate or non-virulent infection, uses the host cell as a haven where it can survive in a latent state. It does not harm the host cell. After the phage DNA is injected into the host cell, it uses integrases encoded by the phage to integrate into the host genome, at which point it becomes known as a prophage.

The host cell divides for the duration that it is there and does not create the proteins necessary to make progeny, at which point the prophage genome is passively copied alongside the host genome. The bacterial hosts are typically somewhat unaffected by this procedure because the phage genome is typically quite tiny.

I understand the question you are looking for is this:

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.

DNA replication

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.  All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:

cell division during tissue development and repair, and it also guarantees that each new cell gets a copy of the DNA.

A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.

These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.
