Which molecule is used to tell tRNA which amino acid is needed?
A. rRNA
B. mRNA
C. siRNA
Answer:
B. mRNA
Explanation:
anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries.

B. mRNA
Explanation:
The mRNA is used to tell tRNA which amino acid is needed.
Explain what happens to an animal cell when it removed from an organism and placed into distilled water
Answer:
I think it has to do with osmosis
Explanation:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
When a cell is placed into distilled water, hypertonic solution takes place.
A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.

a weather station predicts that warm, humid air will pass over much cooler land
Answer:
This happens when the air has a lot of moisture and when the temperature is low (because in this way the water in the air condenses). So if a weather station predicts that warm humid air will pass over much cooler land, the precaution must be to use healights and drive slowly because it will probably be dense fog.
Fungi live by
A. Making their own food.
B. Eating other organisms.
C. Sucking up nutrients made by other organisms.
Answer:
C
Explanation:
Fungi are heterotrophic.
Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. Most fungi are saprophytes, feeding on dead or decaying material.
Answer:
C. Sucking up nutrients made by other organisms.
Explanation:
Fungi (singular: fungus) are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem.
It could be other plants or animals where they get a great place to source their food.
During this time, the fungi kind of hibernates until they get a suitable and beneficial place they can transfer to.
Fossil evidence has demonstrated that birds evolved from a group of small carnivorous dinosaurs. Scientists have hypothesized that some evolved into birds as they filled available niches. The most recent fossil discoveries have filled in many of the gaps in the evolution of birds from dinosaurs. Before the latest fossils were found, there were some scientists who questioned this idea that birds evolved from dinosaurs. In general, scientists constantly work to
Answer:
To find out the relationship of birds from dinosaur.
Explanation:
Scientists constantly work to find out the evolution of birds from dinosaur and relationship exist between them. Scientists do hard work in order to find out the evidences that shows and confirm the relationship of birds and dinosaur. These new discoveries provides evidences about the evolution and relationship between birds from dinosaur so we can conclude that scientists constantly find out the relationship between these two organisms.

56:47 If you wanted to increase your muscular endurance, it would be important to participate in activities that __________. A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle B. decrease the amount of fuel that the muscle can store and increase the time it takes for the muscle to contract C. increase the number of muscles and decrease the size of the muscle cells D. decrease the length of the muscle and increase the thickness of the muscle
Answer:
The correct answer is - A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle.
Explanation:
Muscular endurance is the ability of a muscle to do some work or exert force continuously and rapidly for a period of time. To increase muscular endurance no heavy exercise required by including exercises that can help in increasing the size of the muscle cells and the amount of blood that is delivered to the muscle. The size of cells and delivering a high amount of blood helps in getting more oxygen and perform the metabolic activity more and generate more energy. So including the exercise rapidly and continuously will help in increasing the muscle cells.

Meiosis in males produces four identical sperm cells.
A. True
B. False
Answer:
B. False
Explanation:
Meiosis in males, not produces four identical sperm cells.
Meiosis is a type of cell division which involves the reduction in chromosomal content to half. The four daughter cells formed in meiosis are not identical. Thus, the given statement is false.
What is Meiosis?Meiosis is a type of cell division in which the number of chromosomes reduces by half than that present in the parent cell and produces four haploid gamete cells. This process is required to produce both male and female gametes- egg and sperm cells for sexual reproduction.
During the telophase II- last phase of meiosis, cell division is incomplete without another round of cytokinesis. Once the cytokinesis is complete there are four daughter cells, each with half a set of chromosomes (haploid) which are different due to the crossing over between chromatids.

❗️❗️EARTH SCIENCE CLASS ❗️❗️Climate factors are the things that established and have changed the Earths climate for billions of years. Which one does include changing the amount of CO2 in our atmosphere
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay, or release gas), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement. Which this also adds to the temperature increase around the world due to our atmosphere keeping all of this CO2.
