What is the function of the macromolecule subunit below?

1. They both involve duplication of a cell's DNA content.

2. Mitosis is for asexual reproduction and meiosis is for sexual reproduction.

3. Mitosis produces 2 cells and meiosis produces 4.

Meiosis and Mitosis both are the cell divisions which involve karyokinesis followed by cytokinesis. Meiosis is different from mitosis in the ploidy of the offspring produced. Meiosis involves 2 divisions whereas mitosis involves only one division. Four daughter cells are produced through meiosis whereas only two are formed from mitosis.

Cell division occurs in a cell through two processes which include Mitosis and Meiosis. Generally, all the cells undergo mitotic division whereas meiosis occur in the organisms which reproduce through sexual mode of reproduction.

Mitosis is the process through which a single parent cell divides to make two new daughter cells which contains equal amount of genetic material as that of their parents. Thus, called as equational division. Here, each of the daughter cell receives a complete set of chromosomes from the parent cell.

Meiosis is a special type of cell division also called as reductional division. This division occurs in the germ cells in the organisms which reproduce through sexual mode of reproduction for the production of gametes, such as sperm or egg cells. These gametes are haploid in nature as they receive only half of the set of chromosomes from the parent cell. Meiosis involves two rounds of divisions which ultimately result in the formation of four cells with only one copy of each chromosome.

Explanation:

Feature like green forested regions and its beautiful scenery supports his conclusion that the Rockies were relatively young mountains than black East.

Answer:

The types of point mutation depicted are:

1. C. Silent mutation

2. B. Nonsense mutation

Explanation:

Point mutation is known to be a mutation that actually affects a single nucleotide and it has to do with the substitution of one base for another. This substitution can occur by changing, inserting or deleting a DNA or RNA sequence. A nonsense mutation refers to a change in DNA which leads a protein to either terminate or end its translation so quickly than expected. This mutation is commonly seen in humans.

Silent mutation is known to be the mutation in DNA  whereby there are no effects which are observable in an organism's phenotype. This type of mutation are seen as a specific type of neutral mutation.

Answer:

Velocity is a speed while force is a push or pull.

Explanation:

Velocity refers to the speed of an object in a specific direction whereas force is a push or pull in order to move an object one place to another. When we apply force on an object, the object moves in the direction of force applied so this moving is known as velocity. The unit of velocity is meter/ second whereas unit of force is newton which is equal to kilogram meter / second square.

Answer:

Due to presence of single stranded.

Explanation:

RNAs structural weakness a big strength due to the presence of single stranded instead of double stranded. This single stranded helps RNA to occupy less space and utilize less energy for replication as compared to double stranded that occupy more space and use more energy for replication. So we can conclude that the structural weakness of RNA provides big strength to RNA.

Answer: Expectation is that 75% of offspring will have the dominant phenotype, 25% the recessive phenotype.

Explanation: Pp x Pp gives expected offspring genotypes PP (25%), Pp (50%), pp (25%).

If P is dominant, the expectation for phenotype ‘P’ = 75% and for phenotype ‘p’ = 25%

Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.

Therefore two Lithium atoms bond with one oxygen atom to form Li2O

Carbon-neutral refers to balancing out the overall quantity of carbon emissions.

Carbon balance, the situation where a person, company, or organization releases no net carbon into the environment. Lowering carbon emissions and using carbon offsets to offset emissions are two ways to do this.

Net-zero carbon indicates no carbon was emitted from the beginning, hence no carbon has to be caught or offset when the term "carbon-neutral" refers to balancing out the overall quantity of carbon emissions.

For instance, a business might declare it  to be "zero carbon" if its building runs solely on solar power and consumes no fossil fuels.

Therefore, carbon neutrality means no net carbon in the environment.

This question is incomplete as it lacks some parts. The missing part is as follows:

" Scientists have used genes from spiders to genetically engineer goats that produce silk strands along with their milk".

The answer is Spider silk proteins can now be produced in large quantities without killing spiders to obtain them.

Explanation:

The procedure in this question is describing genetic engineering/modification, which involves manipulating the genome of an organism in order to obtain desirable traits. In this case, certain genes from spiders have been used to genetically modify goats, which now produce silk strands along with their milk.

This process means that silk proteins, which is naturally produced by spiders, can now be produced in large quantities without having to kill spiders to get it since it will nor be produced alongside milk by GM goats.

Answer:

Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes. They are so hot and choking that if you are caught in one it will kill you. ... Some of the good ways that volcanoes affect people include producing spectacular scenery, and producing very rich soils for farming.

:))i forgot to add... Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields.

A volcanic eruption on the mainland of the U.S. could potentially disrupt transportation, power and communication systems, cause damage to infrastructure and homes, and create hazardous air and ash conditions, potentially affecting daily activities such as commuting and accessing necessities.

A volcanic eruption on the mainland of the U.S. could have a significant impact on daily life, depending on the location and severity of the eruption. If the volcano is located in a heavily populated area, it could cause widespread destruction, loss of life, and displacement of residents. The ash and debris from the eruption could also cause damage to infrastructure, making it difficult to travel, communicate, or access essential services.

Additionally, a volcanic eruption could cause power outages, water shortages, and other public health and safety concerns. If the eruption is severe enough, it could disrupt food production and transportation, leading to shortages and rising prices. If the eruption occurs in a less populated area, it may not have as much direct impact on daily life, but it could disrupt travel and commerce, and cause air and water quality issues.
