What is an antigen?
Answer:
In immunology, an antigen is a molecule or molecular structure, such as may be present on the outside of a pathogen, that can be bound by an antigen-specific antibody or B-cell antigen receptor. The presence of antigens in the body normally triggers an immune response.
what happans to DNA inside the necleus before meiosis begins?
Answer:
Before mitosis begins, the cell has already made new copies of each of its chromosomes. However, these new copies remain attached to the original chromosome. A dividing cell must be able to pull the copied chromosomes apart from the original copies, which is how the DNA is evenly divided when one cell splits into two.

Select the tubes that contain protein.
Select all that apply.
Tube 1: Pepsin
Tube 2: Albumin
Tube 3: Starch
Tube 4: Water
Answer:
Tube 1: Pepsin
Tube 2:Albumin
Explanation:
The tubes that contain protein are TUBE 1 : PEPSIN and TUBE 2 : ALBUMIN
Pepsin contains inactive protein called Zymogen also called pepsinogen.
Albumin is the single most abundant protein which is produced in the liver.
Starch does not contain protein but sugar which yields Carbonhydrate.
Tube 4 : contains water which is also a form of nutrient different from protein.
Therefore, the tubes that contain protein ARE tube 1 and tube 2 : PEPSIN and ALBUMIN.

Describe how carbon is cycled through the environment in the carbon cycle. Include an explanation
of how photosynthesis, cellular respiration, and carbon dioxide are involved in the carbon cycle.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Name the three types of population distribution,
describe each, and explain the conditions that
govern each.
Answer:
random clumped uniform i think
Explanation:
Answer:
The three types of population distribution are uniform, random, and clumped.
Uniform distribution is rare. Individuals are evenly spaced and there is fierce competition for resources.
In random distribution, some individuals are close together, and some are spread apart. This occurs when there are sufficient resources available.
In clumped distribution individuals are clustered around patchy resources. This is the most common type of distribution.

Explain the effects of air pollution on several European countries. (Site 1)
Answer:
Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.
Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.
"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

Identify Organelles in an Animal Cell
Answer:
A- Nucleus
B- Lysosome
C- Ribosomes
D - Centrioles
Explanation:
Got it right on edge2021
The cell organelles in an animal cell are Label A: Nucleus, Label B: Lysosome Label C: Ribosomes, and Label D: Centrioles.
Digestive enzymes found in lysosomes break down waste products from cells as well as foreign objects. They are essential for the recycling of cellular parts and preserving cellular homeostasis.
Ribosomes can be found either bound to the endoplasmic reticulum or floating freely in the cytoplasm. They interpret the messenger RNA (mRNA)-encoded genetic instructions and produce proteins in accordance.
Centrioles are essential for the development of the mitotic spindle, which helps separate the chromosomes during cell division.
Additionally, they play a role in the development of cilia and flagella, which are critical for some cell types' ability to move and perform sensory tasks.
Thus, the answers are nucleus, lysosome, ribosome, and centriole respectively.

If a cell has 14 chromosomes, how many chromosomes will each daughter cell have after mitosis and cytokinesis?
Why is this important?
Answer: After mitiosis, each daughter cell will also have 12 chromosomes. Cytokinesis is just the last stage of telophase, where the cell completely forms the two daughter cells. Telophase does not form chromosomes.
Explanation:
If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.
What happens in Mitosis?There are four stages of mitosis: prophase, metaphase, anaphase and telophase.
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres.
2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)
3) Anaphase: sister chromatids are pulled to opposite poles of the cell
4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin.
If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.

Eggs and sperm are called gametes. What problem would result if gametes were diploid?
Answer: If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
Explanation:
Answer:
If gametes were diploid, the resulting organism would have too many chromosomes.

Explanation:
what would happen if the igneous rock was first exposed to energy from the sun
Answer:
If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground
Explanation:
Answer:
An igneous rock can change under pressure to metamorphic. A igneous rock can turn into another igneous rock by melting and solidifying, it can turn into a sedimentary rock by getting weathered then recemented, or it can turn into a metamorphic rock by being subjected to great heat and pressure

Answer:
The study of living and nonliving components of a system can be best described as an. ecosystem ... Describe how you could determine the population size of a specific type of plant in a large forest without counting all of the plants
It is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.
This technique is known as quadrat sampling.
Quadrat sampling is a methodology by which organisms of a sample of the habitat are directly counted and then this value is used to calculate the total population of an area, i.e., the total number of individuals/organisms in a given area.
In this case, a quadrat delimits a small area in which the specific plant can be estimated.
The abundance of a population in a particular area can be estimated by using the number found per quadrat and then multiply this value by the total size of the area.
Quadrat sampling is a very useful methodology for the study of biodiversity.
In conclusion, it is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.
