Like most plants, a bluebonnet begins as a seed under a blanket. When the time is right, the outer coat of the seed cracks to releaseee a tiny root tip. As the root tip begins to grow downward, the stem will begin to grow and push upward. How does the bluebonnet root knwo which way is down? How does the stem know whch way to stretch to reach sunlight? The answer is geotropism. This property of plants allows them to orient their growth with the direction of gravity. What phrase helps you determine what orient means? a. Property of plants b. To reach the sunlight c. How does the stem know d. With the direction of gravity
Answer:
d. With the direction of gravity
Explanation:
Geotropism or gravitropism is a coordinated process of plant growth in fungi and plants to respond to the changing gravity. It a general feature that are found in higher and lower altitude plants. The roots show positive gravitropism and the stem negative gravitropism this they appear to be bend upside on a hill or slope. Can be seen with a potted plant, was the woody stems are capable of bending.1-5 plz help me its science
20. A research company wants to design a new type of artificial heart valve that will be less likely to be rejected by a person's immune system. Which step in the design process should the company perform before building a prototype of the heart valve?
A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.
Answer:
C. Determine how to manufacture the new heart valve.
I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.
The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.
What is meant by a Prototype?A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.
A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.
Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.
Therefore, the correct option for this question is C.

The volcano released a lot of sulfur dioxide and ash
According to question, "C" which is the volcano released a lot of sulfur dioxide and ash.
What is a volcano and what causes its eruption?When magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge.
Thus, the volcano released a lot of sulfur dioxide and ash is correct.

Why does it rain more heavily on the windward side of mountain ranges?
A.Air masses absorb moisture as they increase in altitude, form clouds which precipitate rain.
B.Cool air on the lee side of the mountain encounters warm moist air from the windward side causing it to give up moisture.
C.Prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing rain.
D.Cool, moist air from the oceans warms over land and precipitates rain on the windward side of mountain ranges.
It rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.
What are the prevailing winds?This is a type of wind that blows in a specific direction over a certain area, and its strength can be influenced by many factors, like the elevation of the land, temperature and pressure differences between air masses, earth rotation, etc. In a mountain range, the prevailing winds carry moist air to the top of the slope, where it cools and releases precipitation, that causes the rain.
Hence, it rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.

A) chromosome are made of DNA.
B) there are 26 pairs of chromosomes in humans.
C) alleles are the different forms of a gene that can exist.
D)chromosomes contain genes that control the inheritance of traits.
E)genes are made of chromosomes and contain all of the genetic information for an organism.
D)chromosomes contain genes that control the inheritance of traits.
The statements 'chromosomes are made of DNA', 'alleles are the different forms of a gene that can exist' and 'chromosomes contain genes that control the inheritance of traits' are TRUE (Options A, C and D).
Chromosomes are linear fragments of DNA that contain part of the genetic material in eukaryotic organisms.
Alleles are different gene variants. In diploid (2n) organisms, one allele for a given gene locus is inherited from the mother, whereas one allele of the same gene is inherited from the father.
Genes contain the instructions that are inherited across generations in order to synthesize proteins (both structural and enzymatic proteins), which largely determine the phenotypic traits of an organism.
In conclusion, the statements 'chromosomes are made of DNA', 'alleles are the different forms of a gene that can exist' and 'chromosomes contain genes that control the inheritance of traits' are TRUE (Options A, C and D).

Answer:
d. amino acid chains are assembled from information in the mRNA
Explanation:
The ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).
During gene transcription, a sequence of DNA called gene is used as a template to create a messenger RNA (mRNA).Subsequently, this mRNA travels to the ribosome to be used as a template for the creation of a protein by the process of translation.The ribosome is the site where successive amino acids are added to the growing polypeptide according to the order of triplets of nucleotides or 'codons' in the mRNA sequence.In conclusion, the ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).

I need help with my science question Which molecules do cells need to release energy? Here is the choices.Claim 1: Cells need glucose to release energy. Claim 2: Cells need amino acids to release energy. Claim 3: Cells need oxygen to release energy. Claim 4: Cells need glucose AND amino acids to release energy. Claim 5: Cells need glucose AND oxygen to release energy Claim 6: ALL?
Answer:
Claim 5: Cells need glucose AND oxygen to release energy.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, cells need glucose and oxygen to release energy.
The statement 'cells need glucose AND oxygen to release energy' is correct (Claim 5).
Cellular respiration is a series of metabolic reactions by which aerobic cells used oxygen and the energy stored in the chemical bonds of foods (e.g., glucose) to produce ATP.
Cellular respiration has three main stages: glycolysis, the citric acid cycle and oxidative phosphorylation.
During glycolysis, a molecule of glucose is used to create two molecules of pyruvate, which enter into the citric acid cycle.
Oxygen is the last acceptor of electrons in the electron transport chain of oxidative phosphorylation.
In conclusion, cells need glucose AND oxygen to release energy.
