Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

Explanation:
Infer If the rock layers shown above hare
not been disturbed, what type of dating
method would help you determine which
layer is oldest? Explain.
Answer:
radiometric dating methods
Explanation:
The oldest rock layer will be at the very bottom, and as time goes on, more layers will form making the top layer the youngest layer and the bottom layer the oldest. This method can determine the amount of radioactive decay of certain elements which can help them make a geologic time scale.

NEED CORRECT ANSWER ASAPPP
Answer:
D. 4
Explanation:
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface.
From the diagram provided above, the thin beam of light which illustrates reflection is the fourth because as it hit the surface, it bounced back to the medium from which it was originally propagated with.

What are the different types of Adaptations? Give examples of each.
Give an example for natural selection occurring based on food sources
Answer:
Behavioural-made by an organism that helps it to survive/reproduce.
Physiological-a body process that helps an organism to survive/reproduce.

Explanation:
two difference between drone bee and worker bee
Answer:
The worker bees are female, but they do not breed. The queen bee is female and creates all the babies for the hive. The drone bees are male and do not have a sting. Bees communicate with each other about food sources using dances.
Explanation:
What is Natural Selection? Give an example for Natural Selection for Survival.
Answer:
is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds
Explanation:
It's sorta like adapting with extra steps.
Answer: Natural Selection
Explanation: Individuals in a species have variation or mutations.
These differences may either be helpful, such as a giraffe with a long neck, or unhelpful, such as a colour variance in a moth that makes them stand out to predators.
The individuals that are more suited to their environment will survive and breed, passing on their genes.
Those that are not suited will die and their genes will not be in the ‘gene pool’.
This is the survival of the fittest!

What is the role of deoxyribonucleic acid (DNA) in organisms?
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
Explanation:
hope you like my answer
Answer:
The DNA carries your "information" about yourself and contains the biological instructions that make each species unique in their own ways
Explanation:

How does a bird develop?
Answer:
All birds start their lives inside an egg. When some birds hatch from the egg they are covered in downy feathers, and they are able to run around and find their own food. Many ground-living birds, such as pheasants and ducks, develop in this way.
Which recent discovery led to a new understanding of how genetic mutations increase the risk of cancer? double helix structure of DNA BRCA1 and BRCA2 genes nucleic acid monomers formation of tumor suppressor proteins
Answer:
BRCA1 and BRCA2 genes
Explanation:
The BRCA1 and BRCA2 genes are tumor suppressor genes that encode breast cancer susceptibility proteins involved in repairing double-strand DNA breaks (DSBs) by the mechanism of homologous recombination. This mechanism uses the sister chromatid of the homologous chromosome as template for repairing DSBs. It has been shown that mutations in BRCA1 and BRCA2 genes alter the molecular mechanism of homologous recombination DNA repair, thereby mutations are not repaired appropriately and persist in the DNA of tumor cells.
(B.) BRCA1 and BRCA2 genes

define magnification and cisternae?
Answer:
Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.
Explanation:
It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".
A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.
Question: How is it that traits can vary so much in the same family?
Answer: One component, called shared environment, includes all environmental influences that make children in a family similar to one another.
Explanation: Environmental variance not due to shared environment is called nonshared environment; this portion of environmental variance makes family members different from one another.

How could you determine the identity of a bacterium?
Answer:
THE RELATIONSHIP OF IDENTIFICATION TO BACTERIAL CLASSIFICATION AND NOMENCLATURE. In order to identify an unknown bacterial isolate, the characteristics of the isolate must be compared to known taxa. In microbiology, the basic taxonomic unit is the species, and groups of related species are placed in the same genus.
If I wanted to prepare to run a marathon, what type of macromolecule would I want
to consume?
Answer:
Complex Carbohydrates
Explanation:
There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.

this blood vessel?

magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.
Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

True or false
Answer:
True.
Explanation:
Earthquake proof buildings are those which have the ability to stand during an earthquake. Shock absorbers that is present between the building and the ground motion, able the building to remain upright during an earthquake. The shock absorbers has the ability to absorb all the disturbance produced in the building and for that purpose the building is safe.
