What type of molecule is produced by the ribosome?
A. DNA
B. RNA
C. protein
D. all listed
Answer:
The correct answer is - C. protein.
Explanation:
Ribosomes are biological molecules that are made up of RNA and proteins. These molecules produce protein molecules with the help of mRNA by the process of translation. These molecules are called the factory of protein or protein synthesis site.
The RNA that is present in these molecules is ribosomal RNA. These are attached to the other cell organelles called endoplasmic reticulum used the protein to check and modify them.

What describes the goal of genetically engineering crops?
Answer:
Genetically modified crops (GM crops) are those engineered to introduce a new trait into the species. Purposes of GM crops generally include resistance to certain pests, diseases, or environmental conditions, or resistance to chemical treatments (e.g. resistance to a herbicide).

a.) Give one example of how animals respond to their environment
b.) Give one example of how plants respond to their environment
Answer:
1. Animals may to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather some animals will hibernate. Examples of hibernating animals maybe ants, snakes, black bears, beavers, and ground squirrels.
2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.
Explanation:
Answer:
a) For example, a cat may see a saucer of milk. Information from
the cat’s eyes travels along nerve cells to the brain, where the brain
processes the information. If the brain decides it wants the milk,
the brain sends a signal to the muscles in the cat’s limbs, and the cat
moves to the saucer of milk and drinks it
Explanation:
b) For example,
specialized cells in the leaves of trees detect the decrease in sunlight
as winter approaches. Chloroplasts then reduce production of green
chlorophyll. As existing chlorophyll is broken down, other coloured
particles are revealed, creating the beautiful red- and orange-coloured
leaves we see during autumn. Th e leaves eventually die and fall off . In
the spring, increased sunlight and warmer temperatures promote the
production of new leaves containing large amounts of chlorophyll, and
the green colour returns to the leaves.
Mitosis ans meiosis are both ways in which cells___?
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Explanation:
10. Why are most species that have ever lived on Earth extinct?
Explanation:
At least 571 species have been lost since 1750, but likely many more. The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.
Answer:
Some animals have gone extinct due to over hunting on them for skin, while some have died of because they weren't able to adapt to their environment because it change over time, causing them to go extinct

Parenchyma is a simple permanent tissue and xylem is a complex
permanent tissue.
Answer:
Explanation:
This is parenchyma is found below the epidermis of plants and It of living cells that have thin cell walls which are loosely packed to accommodate the intracellular space. Parenchyma consist of chlorophyll and they take part in photosynthesis.
Xylem is called a permanent tissue because it contain various types of cells like tracheids, vessels, xylem fibres, xylem parenchyma which is responsible for storing food.
Can anyone tell me how old this bird is. We found it outside.
Humans, like other organisms, require energy for growth and repair. When cells create ATP for energy, carbon dioxide is produced as a waste product. How does the body respond to this process in order to maintain homeostasis?
Answer:
The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.
Explanation:
Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:
1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.
2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.
3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.
