if one centromere on each chromosome is needed for proper cell division, what would you expect to happen to cells that have the products with 2 centromere

Answers

There will be incorrect splitting or dividing of the chromosome, if this were to occur, producing chromosomal errors. Certain portions of the chromosome will be moved into one and the other incomplete sets of genes will be transferred.

Nondisjunction or incorrect ploidy of chromosomes will result, causing the organism to not live depending on the severity of the genes.

Name the two types of vectors.

Answers

Two types of vectors are Biological and Mechanical.

Vectors are important agents for cloning in biotechnology. Plasmids and bacteriophages are the two types of vectors.

What are vectors?

Vectors are the important tools used in biotechnology for cloning the desired DNA sequence or a segment of gene in a host organisms.

Vectors are ideal for cloning as they are small in size and they have the unique ability of self-replication. Thus, they can efficiently multiply in the body of host.

Vectors also possess restriction enzymes which make them cleave at specific sites and thus it can be ideal for drug selection. Another important feature of vectors is that they do not pose any interference with the DNA of the host.

Yeast cells, bacteriophages and plasmids are the commonly used vectors in genetic engineering. Plasmids are widely used vectors isolated from bacteria. Bacterial artificial chromosomes and Yeast artificial chromosomes are also popularly used vectors for genetic modifications.

Thus, vectors are ideal and important for genetic engineering processes.

C. Several
D. A lot

Answers

The answer is C. Several.

Answer: Option A; Only one

Explanation: Niche is space where the organism has a functional role. In a niche, only one species can exist, this is because if there are two species, there will be competition between them. In such a case, the species which will dominate, it will affect the survival of the other weaker one. This way, only one species will exist.

Which of these environmental changes occurs most rapidly?

A.) Forest Succesion

B.) Human Population Growth

C.) Decomposition

D.) Tornado

Answers

I think it's B the population changes each second.

The environmental change that occurs most rapidly among the options listed is human population growth (Option B).

What are environmental changes?

Environmental changes refer to alterations in the natural world caused by a variety of factors, including natural forces and human activities. Environmental changes can be gradual or rapid, short-term or long-term, and can affect both living organisms and non-living things.

While the other options - forest succession, decomposition, and tornado - can occur relatively quickly in their own right, they are typically on a much shorter timescale compared to the exponential growth of human populations.

Human population growth has the potential to lead to significant environmental impacts, such as increased resource consumption, habitat destruction, and pollution, among others.

Therefore, it is essential to manage human population growth in a sustainable way to ensure the long-term health and wellbeing of both humans and the planet.

Environmental changes can have significant consequences for both human populations and natural ecosystems. They can lead to the extinction of species, increased frequency and severity of natural disasters, changes in weather patterns, loss of biodiversity, and disruptions to food and water supplies.

Archeologists have unearthed the tombs of thousands of workers. The author suggests that these tombs belonged to the workers who built the pyramids. What reasoning does she use to support this claim?

Answers

You could argue with the fact that a common worker was allowed their own burial tomb. Back in ancient Egypt few were rich enough to have a Tomb built. Also the tomb seams to be a graveyard, which implies that this is a place specifically designated for the dead, which were usually not tombs but in places closer to town.

In addition to the tombs, archeologists have also discovered a large number of bakery sites near the Great Pyramid. In fact, there are enough bakeries to provide food for thousands of workers, which is how many it would take to construct the Great Pyramid.

Final answer:

A medicinal chemist like Dorothy in a pharmaceutical company can have many tasks, but one potential assignment could be designing and synthesizing new drugs. This involves identification of potential targets, computer simulations for molecule design, lab synthesis and testing

Explanation:

As a medicinal chemist working in a pharmaceutical company, Dorothy would have a variety of tasks. One potential assignment could involve designing and synthesizing new drugs to treat specific diseases. This usually starts with research to identify potential biological targets for a drug (such as a protein involved in a disease process). Once a target has been identified, she would then conduct computer simulations to design a molecule that can interact effectively with that target. The next step would be to synthesize the drug in the lab, and then conduct tests to determine its effectiveness, safety, and side-effects.

Answers

Final answer:

Wind, friction, and the Coriolis effect combine to move water in a direction that is perpendicular to the wind due to the Coriolis effect and the Earth's rotation.

Explanation:

Wind, friction, and the Coriolis effect combine to move water in a specific direction. The correct answer to this question is B. Perpendicular to the wind. This is due to the Coriolis effect, which makes moving objects veer to the side because of the Earth's rotation. The combination of the wind (which pushes the water), the Coriolis effect (which turns the water to the side), and friction (which slows the water) creates a net movement of the water perpendicular to the wind's direction.

The index fossils have already established relative age. It is for that reason they can be used to estimate the age.

An index fossil is a fossil that spans a particular geologic time and/or given environment.

These types of fossils (index fossils) can be any type of preserved remains of an organism that lived on the Earth (e.g., an animal or plant).

The population will increase in size. Therefore, the correct option is option B among all the given options.

What is population?

In human biology, population refers to the total population of a region (such as a nation or the entire world), which is always changing due to both gains and losses (such as births and immigrations). The availability of food, the impact of diseases, and various other environmental conditions all have an impact on the size of the human population, just like they do for any other biological species.

Social norms governing reproduction and technological advancements, particularly in medicine & public health, which have decreased mortality and increased life expectancy, have an additional impact on human populations. The population will increase in size.
