Which of the following are the main external stimuli to which plants respond?
Check all that are true.
touch
light
oxygen
gravity
Plants primarily respond to touch, light, and gravity as external stimuli, using sophisticated systems like photoreceptors for phototropism and amyloplasts for gravitropism.
The main external stimuli to which plants respond are touch, light, and gravity. Oxygen is not typically considered a directional stimulus for plants. Plants have developed sophisticated systems to detect and respond to their environment. Phototropism is an example of how plants grow towards light using photoreceptors like cryptochromes and phototropins. Gravitropism describes how plants sense gravity; shoots exhibit negative gravitropism growing away from gravity, while roots exhibit positive gravitropism and grow towards gravity. In response to touch, certain plants can exhibit rapid movements or slower growth alterations, known as thigmotropism and thigmonasty.
Explain why the size of your muscles is the is partly an acquired trait and partly dependent on DNA
Answer:
The size of the muscle is partly dependent on the DNA and exercise.
This is because DNA traits is actually responsible for how a muscle formed in the body. This trait is usually gotten from the parents of the offspring.
In the same vein, exercises can also be responsible for the size of an individual’s muscle. Exercises help in the expansion and building of muscle tissues which makes it bigger.
The male cardinal is bright red. The female is a dull brown. Why are the two birds different colors?
Given two areas with equal sunlight and available water. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide.
How does the rate of photosynthesis in Area I compare to that in Area II?
Atmospheric carbon dioxide has no effect on the rate of photosynthesis.
The rate of photosynthesis increases with a decrease in carbon dioxide.
The rate of photosynthesis increases with an increase in carbon dioxide.
The level of carbon dioxide increases with the level of available oxygen.

Plant and animal cells, while both eukaryotic, each have distinguishing characteristics. For example, plant cells contain chloroplasts, while animal cells do not. Which statement BEST elaborates on the reason for this difference?
A) Chloroplasts are needed for plant cells to rid themselves of waste. Animal cells do not produce any waste.
B) Chloroplasts help plants make their own food by converting light energy. Animals do not make their own food.
C) An animal cell has a cell wall, while a plant cell does not. Instead, chloroplasts line the outside of plant cells.
D) The DNA in an animal cell is housed in a nucleus, but plant cells do not contain nuclei; it is stored in chloroplasts.
The right option is; B) Chloroplasts help plants make their own food by converting light energy. Animals do not make their own food.
Plant and animal cells are eukaryotic cells (cells that have a definite nucleus and membrane bound organelles). The two cells are similar structurally, and functionally, but a few significant differences exist in each of them. Plant cells have chloroplasts (organelles that contain chlorophyll which absorbs sunlight) it uses to produce its food though photosynthesis. Animal cells do not have chloroplast. It uses mitochondria (an organelle that produces energy through respiration) to produce most of the cells energy from food. Mitochondria is also present in plants cells but it does not have the same function in plant cells.

Why is cell specialisation (differentiation) important for the development and growth of a healthy baby from a fertilised egg? Please help!
Answer:
Cell specialization is important in the development and growth of a healthy baby because cells differentiated to form different tissues, which organizes themselves to forms organs.
Explanation:
The development of an organism is divided into two processes, differentiation, and growth. The body contains two types of cells undifferentiated cells can become any cells, while differentiated cells have a specific role. Differentiation is the process in which cells change from an undifferentiated cell and become specialized (differentiated cell). On the other hand, growth is the process by which already differentiated cells reproduce to increase the size of the tissue.
Why is it important that scientists haven’t identified a Lokiarchaeota cell yet
Answer:
Scientists have evidence that Lokiarchaeota cells exist from genetic information, which they can compare to other species of microbes. However, they don’t yet have an actual cell to confirm what the cells actually look like.
Explanation:
If scientists were able to stop the tectonic plates from moving, people on Earth would no longer have
bacterial cells may have all of the following except a
a. Glycocalyx
b. nuclear membrane
c. cytoplasmic membrane
d. peptidoglycan cell wall
A Bacterial cell may have all of the following except a nuclear membrane. Thus, the correct option for this question is B.
What is Bacteria?Bacteria may be defined as a type of unicellular microorganism that significantly lacks a well-defined nucleus and other membrane-bound cell organelles.
The cell wall of bacteria is made up of peptidoglycan. It is an essential protective barrier for a bacterial cell that surrounds the cytoplasmic membrane as well. The Glycocalyx is the outermost layer of the three-layered cell envelope found in many bacterial species. It limits the access of certain molecules to the extracellular membrane.
The cytoplasmic membrane in the bacteria is composed of an approximately equal proportion of lipids and proteins. Phospholipids are the main lipid components.
Therefore, a nuclear membrane is significantly not present in bacterial cells. Thus, the correct option for this question is B.

Where was the waste and garbage dumped from the town and factory in the lorax?
Answer:
River
Explanation:
All the waste generating from increased industrial production or increased population in the town was dumped into the river stream.
This open dumping into the river not only contaminated the water body but also caused nuisance as it led to arise of infection and diseases.
Due to all such incidences, the town soon converted into ghost town and it soon became inhabitable.

What would happen to a cell if cellular respiration stopped?
A. The cell would use water for energy.
B. The cell would not produce enough ATP.
C. Glucose breakdown would increase.
D. ATP production would increase significantly.
Answer:
B
Explanation:
Cellular respiration includes glycolysis that occurs on the cytoplasm of cells and Krebs cycle that occurs in the matrix of the mitochondria. The whole cellular respiration metabolic pathway produces a net of 36 ATPs (glycolsys produces a net of 2 ATPS and Krebs cycle a net of 34 ATPS). They use glucose as a substrate to harness the energy in its chemical bonds to produce the store this energy in ATPs, the energy currency of cells.
If cellular respiration stopped in a cell, it would lead to a lack of ATP production and energy for the cell's functions, the halt of pyruvate, citric acid, and carbon dioxide production, and a decrease in ATP production since glucose could not be broken down.
Explanation:If cellular respiration stopped in a cell, several things would happen.
ATP would not be produced, which means the cell would not have the energy it needs to carry out its functions.The production of pyruvate, citric acid, and carbon dioxide would also be halted, as they are products of cellular respiration.Additionally, without cellular respiration, the cell would not be able to break down glucose for energy and would experience a significant decrease in ATP production.In a strike-slip fault, the rocks on either side of the fault slip past each other sideways.
