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.

George is interested in insects and wants to do an experiment. Which of the following is a scientific question about insects that he could investigate with an experiment?
A. Do ants feel anxiety?
B. Why are there so many different kinds of insects in the world?
C. Are ladybugs prettier than beetles?
D. Do different food types affect the growth rate of beetles?
Answer: D. Do different food types affect the growth rate of beetles?
Explanation:
A scientific question can be define as the question that can be answered using the scientific methodology. The scientific methodology is based on the series of steps like making observation based on the question, composing the hypothesis, testing the hypothesis by using the experimentation process, concluding the results.
D is the correct option. This is because of the fact that growth rate of the beetles can be examined on the basis of different food types.
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.

Explanation:
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.

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.
What are the four functions of the digestive system?
The digestive system involves all organs responsible for digestion. The four functions of the digestive system are digestion, absorption, excretion and assimilation.
What is digestion?Digestion is the breakdown of complex food materials into their simplest form, which is done by digestive system.
The main functions of digestive system are:
Digestion: breakdown of food.Absorption: The absorption of simple food into blood.Assimilation: movement of digested food molecules into the cells and are used. Excretion: the elimination of waste materials.Thus, these are the four functions of digestive system.

What can happen when you have taken much more than the normal amounts of vitamins?
Answer:
Taking vitamins is a daily routine that has millions of people around the world. However, taking too many vitamins can lead to an overdose and be dangerous to health.
Explanation:
For example, water-soluble vitamins (vitamin B1, B2, B3, etc.) are excreted from the body and are not stored in the tissues. However, an overdose of some of these vitamins can induce side effects, such as irreversible nerve damage, or liver damage.
Meanwhile, fat-soluble vitamins (vitamin A, D, K, etc.) do not dissolve in water and can be stored in your body's tissues. Due to the accumulation of these vitamins, they are likely to produce toxicity or harmful effects much more than water-soluble vitamins.

Two or more organs working together form A) tissue. B) a group. C) a system. D) an organism.
Organs working together will form an organ system. Therefore ,option (C) a system is correct.
What is an organ system?An organ is a collection of tissues that work together to do its job, and an organ system is a group of organs that work together to do a certain job. There are eleven organ systems in a human body.
The respiratory system, the digestive and excretory system, the circulatory system, the urinary system, the integumentary system, the skeletal system, the muscular system, the endocrine system, the lymphatic system, the nervous system, and the reproductive systems are all considered to be part of the 11 organ systems.

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.
In what situation does anaerobic respiration take place
Explanation: APEX answer
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.is water found only in one state
