True or False:
Bacteria are Eukaryotes.
Answer:
Bacteria belongs to the Prokaryotes family of microorganisms.
Explanation:
The answer is false.
The given statement is False as the Bacteria are prokaryotes usually.
What are Prokaryotes?The cells falls majorly under two categories:
- Prokaryotes and
- Eukaryotes
The single celled bacteria falls under the category of Prokaryotes.
Components of Prokaryotes are:
These cells share common component with Eukaryotes such as
- Plasma Membrane which is an outer covering separating the cell's interior from its surrounding environment.
- Cytoplasm containing cellular components.
- DNA
- Ribosomes, helpful in synthesis of proteins.
A prokaryotic cells is simple, single celled organisms lacking nucleus or other membrane bound organelle.
Prokaryotic DNA is found in the central part of the cell in the darkened region called the Nucleotide.
The diameter of these cells are smaller than Eukaryotes and allows ion and organic molecules to quickly spread to other parts of the cell.
What are Eukaryotes?A eukaryotic cell has a membrane bound nucleus and other membrane bound compartments or sacs called organelles having specialized functions.
The word eukaryotes meant true kernel or true nucleus due to presence of membrane bound nucleus in these cells.
These are found in higher level organisms including plants, animals and humans.

How would you use the water cycle in your rainforest biome?
Answer:
The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.

Cellular respiration is similar in both plants and animals in what way?
A. Energy is required and oxygen is released
B. Nitrogen is required and energy is released
C. Oxygen is required and energy is released
D. Oxygen is required and nitrogen is released
Answer:
C
Explanation:
cellular respiration is the process of taking organic molecules like C6H12O6 and breaking them down for energy, ATP. Regardless of whether cellular respiration occurs in plants or animals it is the same process, just plants get their C6H12O6 from photosynthesis while animals get it from food
what would happen if a sex cell could not complete DNA replication?
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!

What does it mean if elements are in the same period
Enter text here
Answer:
--> 12.011 is the relative atomic mass number of carbon.
--> elements in the same group have the same number of electrons in their outermost shells
--> elements in the same period have the same number of electron shells.
Explanation:
An element is a pure chemical substance that contains the same type of atoms which cannot be broken down into smaller substances by any chemical reaction. Example of an element is Carbon, hydrogen, Helium, Nitrogen.
Carbon has the relative atomic mass number of 12.011 in the periodic table. This is as a result of carbon having six protons, six neurons and six electrons. Carbon being an element that has isotopes, the number of decimal seen is its relative mass compared to 1/12 the mass of one atom of carbon-12.
Periodic table shows the properties of elements that vary in a regular manner. The elements in the same GROUP have the same number of electrons in their outermost shells. Electrons are arranged in shells which forms the outermost part of an atom around the atomic nucleus. Electron are arranged in shells called K,L,M,N outward from the nucleus with maximum number 2,8,18,32 respectively. For example, atoms in group 1 include hydrogen, Lithium, Sodium and potassium. When arranged in shells, they all have the same number remaining in their outermost shell which is 1. This makes them to have similar chemical properties.
Elements in the same period have the same number of electron shells. Example of elements in the same period include sodium, magnesium, aluminium silicon, phosphorus. When their atoms are arranged in shells, they have the same number of shells irrespective of the atomic number.
Which of the following is NOT evidence for evolution?
A. the fossil record
B. homologous and vestigial structures
C. animals competing with each other
D. animals moving from sea to land
Answer:
C - Animals competing with each other
Explanation:
C is the only one that doesn’t give evidence of evolution
A shows the similarities between the skeletons in different animals. This can help scientists see what organisms have similar structures and what animals they could have evolved from
B shows what organisms could share a common ancestor. Homologous means that the organisms have the same structure in some part of them. Vestigal means the organism has a part to it’s body that is useless. This easily shows what organisms could have a common ancestor
D shows how animals could have evolved from living in the water to being able to survive on land. Pretty self-explanatory
Animals have always competed with each other, so that doesn’t give any evidence of evolution

If a DNA molecule contains 30% cytosine, what % of the molecule should be thymine?
Answer:
20%
Explanation:
cytosine = guanine = 30%
cytosine + guanine = 60 %
adenine + thymine =100% - 60% = 40 %
thymine = 20%
If a DNA molecule contains 30% cytosine, then 20% of the molecule should be thymine.
What do you mean by DNA?DNA stands for deoxyribonucleic acid. It is considered as the genetic material of most organisms. It is a complex molecule that bears genetic information.
Amount of cytosine = 30%
According to Chargaff's rule, A=T, C=G.
∴ Guanine = 30%
Now A + T = 40%
Therefore, the amount of thymine molecules is 20%.

Biomagnification: Hidden Dangers in Food
Webs
Answer:
rfrg
Explanation:
Biomagnification is the process by which toxins and pollutants become increasingly concentrated in the bodies of animals as they move up the food chain. This means that organisms at the top of the food chain, such as humans, can end up with dangerously high levels of these pollutants in their bodies if they consume contaminated prey.
When does this phenomenon is concerning ?This phenomenon is particularly concerning when it comes to certain toxins, such as mercury and persistent organic pollutants (POPs) like PCBs and DDT. These toxins can have serious health consequences, including neurological damage, developmental delays, and cancer.
One example of biomagnification in action is with mercury contamination in fish. Mercury is released into the environment through various human activities, including burning coal and waste incineration. When this mercury enters waterways, it can be transformed into methylmercury, a highly toxic form that accumulates in the tissues of fish and other aquatic organisms.
As larger fish consume smaller fish, the concentration of methylmercury in their bodies increases, leading to dangerously high levels in the bodies of top predators like sharks and swordfish. When humans consume these contaminated fish, they can also accumulate dangerous levels of methylmercury in their bodies.
Similarly, POPs like PCBs and DDT can enter the food chain through contaminated soil and water. As these toxins move up the food chain, they become increasingly concentrated in the bodies of top predators like birds of prey and mammals like seals and polar bears.
These toxins can have serious health consequences for these animals, including reproductive problems and weakened immune systems. When humans consume these contaminated animals, they can also accumulate dangerous levels of these toxins in their bodies.
Biomagnification is a serious issue that highlights the importance of careful monitoring of environmental pollutants and the need for sustainable practices to prevent contamination in the first place.

Answer:
c) The mother cell gives rise to two daughter cells with half the number of chromosomes.
Explanation:
Mitosis is a type of cell division in which a parent cell is divided into two daughter cells having diploid i. e. double number of chromosomes. This type of cell division occurs in the somatic or body cells which is responsible for the growth of that organisms. This mitosis cell division has six phases such as prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Both daughter cells are identical to parent cell.
