one of the kingdoms of living
things?
a Fungi
b. Bacteria
c. Animalia
d. Protista
Answer:
B. Bacteria
Explanation:
Because bacteria are unicellular organisms belonging to the prokaryotic group where the organisms lack a few organelles and a true nucleus
Bacteria is not one of the kingdoms of living things. So, the correct option is (B).
What are the Different kingdoms of Living things?Living things are divided into 5 kingdoms. These are:
1. Monera
It is the kingdom of microscopic living things that groups together prokaryotes (archaea and bacteria) present in all habitats and composed of single-celled things without a defined nucleus. Bacteria belongs to this kingdom.
2. Protista
This group is primitive of eukaryotic which is paraphyletic which includes common ancestor but not all its descendants. Protozoa belongs to this kingdom.
3. Fungi
This kingdom includes yeasts, molds and all species of mushrooms and toadstools, which are multicellular aerobic heterotrophic eukaryotes, have chitin in their cell walls, feed on other living things, and reproduce by means of spores.
4. Plantae
Trees, plants belong to the kingdom Plantae, which is characterized by its sedentary, multicellular and eukaryotic nature. They are autotrophs, whose cells contain cellulose and chlorophyll which are essential for life on Earth as they release oxygen through photosynthesis.
5. Animalia
The kingdom Animalia is divided into two major groups – vertebrates and invertebrates which are multi-celled, heterotrophic eukaryotes that have aerobic respiration, sexual reproduction and the ability to move. This kingdom includes mammals, fish, birds, reptiles, amphibians, insects, molluscs and annelids.
Thus, Bacteria is not one of the kingdoms of living things. So, the correct option is (B).

Give two ways the sperm cell is adapted for fertilisation
Answer: (1) It has a tail to travel to the egg (2) contains a nucleus in the head which will fertilise the egg
Explanation: Firstly it has a tail to help it travel to the egg. Secondly it contains the nucleus in the head that will fertilise the egg. Thirdly the acrosome contains enzymes in order for the sperm to penetrate the egg. Finally, the sperm cell is packed with mitochondria to provide the energy needed to reach the egg.
Sperm cells are highly specialized for the purpose of fertilization. Here are two ways in which sperm cells are adapted for this process: Streamlined shape, Acrosome, and enzymes.
1. Streamlined shape: Sperm cells have a streamlined shape, often described as being tadpole-like, with a long and slender tail (flagellum) and a compact head region.
This shape is adapted for efficient swimming through the female reproductive tract to reach the egg. The flagellum allows the sperm to propel itself with whip-like movements, providing mobility and the ability to navigate through the female reproductive system.
The streamlined shape reduces drag and enables the sperm to move swiftly towards the egg, increasing the chances of successful fertilization.
2. Acrosome and enzymes: The head region of a sperm cell contains a specialized structure called the acrosome. The acrosome is a cap-like structure that covers the front portion of the sperm's head.
Inside the acrosome, there are enzymes, such as hyaluronidase and acrosin, which play a crucial role in fertilization.
When the sperm reaches the vicinity of the egg, the enzymes are released and help the sperm penetrate through the protective layers surrounding the egg, such as the zona pellucida.
Thus, the streamlined shape and the presence of the acrosome with enzymes are two important adaptations of sperm cells that increase their chances of successful fertilization by facilitating efficient swimming and penetration of the egg's protective layers.

A True
B) False
Answer:
The mass of an object is never zero. You measure mass with an ordinary balance on Earth or an inertial balance in space. Weight depends on the effect of gravity, so it can change depending on where it's measured. In the absence of gravity, weight can be zero.

Answer:
I'm pretty sure there would be 1000 guanines in the DNA molecule.
Explanation:
Hope this helps. . . <3
If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.
What will be the total number of thymines if a DNA molecule has a total of 1500nucleotides?The DNA molecules would be given and it have 450 thymines if the DNA molecule has the total of 1500 nucleotides and the DNA molecule also have been known as the deoxyribonucleic acid has been made up of the double helix. The DNA molecule with the total of 1500 nucleotides would contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence, we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
A nucleotide has the monomer constituting DNA or RNA biopolymer molecules and the double-stranded DNA molecule posseses two strands of DNA made up of the nucleotides.
Therefore, If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.

Carbohydrate intake, in particular, can affect performance, with simple carbohydrates and complex carbohydrates having different ideal times for consumption. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores. Sort the following food items
a. Foods rich in simple carbohydrates.
b. Foods rich in complex carbohydrates.
c. Foods without carbohydrates
Answer:
(a.) Foods rich in simple carbs- Low fat smoothie and sport drinks with glucose
(b.) Foods rich in complex carbs- whole-wheat pancakes, whole-wheat spaggetti with marinara sauce and brown rice with vegetables
(c.) Food without carbs- grilled salmon and roasted chicken breast
Explanation:
Simple carbs are easy to digest and eaten before a workout, hence the sports drink and low-fat smoothie falls under that category, while complex carbohydrates are hard to digest...think anything with wheat.

In general, freshwater fish require salinity (salt) levels of 1.0 ppt or lower. You measure the salinity of a freshwater aquarium to be 3.0 ppt. Predict what will happen to the cells of the fish as a result of the salinity level in the aquarium.
1) Is tank water hyper, hypo or isotonic to the fish cells? Explain why.
2) Based on your answer to part 1, what will this type of solution ultimately do to the cells of the fish? ( which way will the water move into or out of the fish cells?)
The cells of the fish will lose water to the aquarium water by osmosis, shrink up, and probably die with time.
1) The tank water is hypertonic to the cells of the fish. Hypertonic solutions are those with higher solute concentrations compared to the sap of the cells placed in them. Hypotonic solutions have lower while isotonic solutions have the same concentrations as the sap of cells placed in them.
2) Because the tank water is hypertonic, the cells of the fish will lose water to the water in the aquarium. When this happens, the cells shrink, and may eventually start dying if the situation remains unchanged enough.

Can someone help me, my paper is due tonight.
Describe solution concentration outside the cell in terms of hypotonic, hypertonic and isotonic.
Answer:
see below
Explanation:
Hypotonic solution is a very dilute solution to the more concentrated solution. Hypo means under . A solution with a lower concentration of solutes than the cytoplasm of a cell, that solution is hypotonic to the cytoplasm. The cell expands as water moves in.
Hypertonic solution is a more concentrated solution to cytoplasm. Hyper means above. A hypertonic solution has higher concentration of solutes than the cytoplasm of the cell. The cell shrinks as its cytoplasm loses water.
Isotonic solution is when two solutions of equal concentration are separated by a semi permeable. Iso means equal. Therefore, in isotonic solutions, water movement out of a cell balances the water movement into it. Cells in the body are usually surrounded by a fluid. The cytoplasm in the cell is usually isotonic to the fluid outside the cell. Hence, no net gain or loss of water by cells.
So, basically, if a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
