Which statement best describes the difference between the crust and the lithosphere?
A. The lithosphere contains both the crust and the upper most rigid layer of the mantle
B. The lithosphere contains both the crust and the inner core
C. The lithosphere contains both the core and the mantle
D. The lithosphere contains both the crust and the ocean

Answers

Answer:

A. The lithosphere contains both the crust and the uppermost rigid layer of the mantle

Explanation:

The statement that describes the difference between the crust and lithosphere is that the lithosphere contains both the crust and the uppermost rigid layer of the mantle.

The earth is divided primarily into 3 concentric layers; crust, core, and mantle. The crust is the outermost layer of the earth. It is a very thin layer. The lithosphere, on the other hand, is the crust plus the upper rigid layer of the mantle. This is the main difference between the crust and lithosphere.

A certain species of lizard comes in three colors: cream, golden, and brown. All lizards are a single solid color (ie, none ever have spots or stripes) You carry out matings between these lizards, and collect the following data:

• Cream and brown lizards can be true-breeding, but golden lizards never breed true.
• Matings between cream and golden lizards always yield cream and golden offspring in a 1:1 ratio.
• Matings between brown and golden lizards always yields brown and golden offspring in a 1:1 ratio.
• Mating golden lizards with other golden lizards always yields brown lizards, golden lizards, and cream lizards in a ratio of 1:2:1, respectively.

Required:
Assign allele symbols to all alleles of the lizard color gene, and indicate which genotypes result in which phenotypes.

Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.

Answers

Answer:

They perform photosynthesis, releasing oxygen into the atmosphere as a by-product.

Explanation:

Around the time that cyanobacteria appear around 3.2 billion years ago, the oxygen levels rise sharply.

Cyanobacteria are photosynthetic organisms. They possess the photosynthetic pigment chlorophyll, meaning they can trap light energy and use it to power chemical reactions to synthesise glucose. They convert carbon dioxide and water into sugar, releasing oxygen into the atmosphere as a byproduct. This causes oxygen levels to rise.

Answer:

Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2).As oxygen photosynthesis starts,that's when the first O2 producing of cyanobacteria occurs.The graph reaches a peak at Cambrian explosion.

With increasing maternal age, the chances of observing trisomies increase significantly. Increasing paternal age is associated with de novo point mutations. Why?

Answers

Answer:

Mother: higher risk of an improper chromosome division

Father: higher risk to suffer point mutations in sperm cells

Explanation:

A trisomy is an alteration in the chromosome number (i.e., an aneuploidy), and occurs when a cell receives three chromosomes instead of two. The risk of aneuploidies -including trisomies- increases with the mother's age due to the fact that older eggs have a higher chance of dividing unequally, thereby leading to an imbalanced number of chromosomes between daughter cells. Moreover, a point mutation is defined as a genetic modification where a single nucleotide is changed in the DNA sequence. It has been shown that point mutations in children are determined to a large extent by the father’s age, which are due to mutations in germline cells (i.e., sperm cells) that were passed to the progeny. A child born from a father who is 20 years old exhibits on average 40 point mutations, whereas a child born from a father who is 40 years old has typically twice the point mutations on its genome.

The climate has three main zones such as tropical, temperate, and polar.

What are Earth's climatic zone?

A climate zone refers to a condition by observing different factors like temperature, humidity, precipitation, season and natural vegetation of an area.

Earth's climate zones is surrounded by the horizontal belts of different climates such as tropical, dry, temperate, continental, and polar zones.

Firstly, Tropical climate zones which present near the Equator of earth and have high temperatures and high precipitation, while Dry or arid climate zones shows high temperatures  and little annual precipitation.

Similarly temperate climate zone observed  Earth’s middle latitudes and shows wider temperature and seasonal variations are more distinct.

Continental climate zone observed in mid-latitudes, shows swing of  temperatures  from cold in winter to warmer, where as polar climate zones shows harsh climate which cannot to support vegetation.

Hence, major zones are tropical, temperate, and polar.

What is the cell cycle?

Lesson Question
Help please !!!

Answers

A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.

how do mutations affect our communications?​

Answers

Explanation:

When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.Over time, a mutation might take place in one of the descendant cells, causing increased activity of a positive cell cycle regulator. The mutation might not cause cancer by itself either, but the offspring of this cell would divide even faster, creating a larger pool of cells in which a third mutation could take place.

7. Cell theory is one of the great unifying theories of biology

Explanation:

Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.

In the question “How does pineapple consumption affect the number of digestive bacteria?”, pineapple consumption is

A) the control group B) independent Variable
C) dependent variable D) experimental group

Answers

Answer:

For the approach of how does pineapple consumption affect the number of digestive bacteria?, pineapple consumption is  the independent variable (option B).

Explanation:

The formulation of a hypothesis is not complete without the existence of the independent and dependent variables, the main variables from the research point of view.

The independent variable is one whose change or modification is capable of impacting the dependent variable, which is one that can be quantified or measured.

According to the approach, if somebody want to know how the consumption of pineapple influences the number of digestive bacteria, the independent variable is the consumption of pineapple, which can be controlled and modified, while the characteristic that is under the influence of this variable is the amount of bacteria, so that the latter is the dependent variable.

The other options do not apply because:

The experimental (D) and control (A) groups refer to the population in which the study is conducted. The dependent variable (C), in this case, is the amount of digestive bacteria.
