A. To attract prey
B. To scare off predators
C. To attract insects
D. To collect more sunlight
SUBMIT
Answer:
c
Explanation:
some plants use this as a way so they could pure insect to trap them and digest them
Plants have specialized cells that produce strong odors to attract insects.
Example:- The inflorescence of the titan arum plant attracts specific pollinators by emitting an intense, carrion‑like odor.Why plants attract insects?Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves.Flowers attract insect for pollination too.

?Which form of energy is NOT correctly associated with the related example
kinetic energy: fat molecules O
potential energy: water held behind a dam o
kinetic energy: movement of muscles
chemical energy: glucose o
Answer:
kinetic energy: fat molecules
Explanation:
Fats store energy so it would be potential.
Kinetic energy: fat molecules
Kinetic energy is the energy that an object or particle uses during its motion. Potential energy is the stored form of energy already present in the object or particle. Chemical energy is the energy stored in the bonds of chemical substances. Water held behind the dam will have potential energy the water currents store energy within them which can be used to move the turbine in the water dam to produce electrical energy. Movement of muscles during walking, running, or performing any other activity which can be seen in the form of displacement from one region to another is due to kinetic energy. Glucose is a chemical molecule whose bonds when broken releases energy in the form of ATP or adenosine triphosphate which is a chemical energy. Fat molecules store energy in the adipocytes in the form of potential energy not kinetic energy. Hence, option kinetic energy: fat molecule is incorrect.Learn more about kinetic energy:

This picture shows different amounts of space in between the particles of two
different soil samples.
Which word best describes what we are seeing?
Answer:
Porosity
Explanation:
I had another question like this and it was B so there u go
Meaning of soil porosity: Pore-spaces, also known as voids, are the area of the soil's volume that is not occupied by solids, either mineral or organic, hence option B is correct.
What is soil porosity?
Under field conditions, air and water are always present in the pore space. The amount of water that a specific volume of soil can hold depends on the amount of pore space.
How many pores, or holes, a soil has is referred to as its porosity. A proportion of the total volume of the soil material is used to measure a soil's porosity.
Soil particles are defined as those that are 2 mm in diameter or smaller and make up the inorganic component of soil. Sand, silt, and clay are the three types of soil particles.
Therefore, Porosity is a crucial indicator in locations where groundwater reserves supply drinking water.

How could an abundance of algae have a positive impact on an ecosystem?
1Algae grow very quickly. An abundance of algae would cover the surface of the water and provide shade for aquatic organisms.
2Algae provide carbon dioxide for many aquatic organisms. An abundance of algae would result in more available carbon dioxide.
3Algae is the food source for many aquatic organisms. An abundance of algae would mean more available food.
4Algae is a primary consumer. More algae would result in a more balanced ecosystem.

leaves of cactus are modified into thorns
Answer:
To reduce loss of water through transpiration leaves of cactus plants are modified into spines.
Explanation:
Answer:
leaves are reduced to spines in a cactus , so that the water does not get evaporated with the heat of the SUN. 1. They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines

How is cellular respiration and photosynthesis linked to specific organelles within the eukaryotic cells?
Answer:
Respiration. The energy collected in the chloroplasts is used during cellular respiration. ... The carbon dioxide and water produced are transferred back to the chloroplast where they are again used for photosynthesis. Cellular respiration takes place in another organelle called the mitochondria.
Explanation:
The mitochondria and cytoplasm is responsible for cellular respiration and the chloroplast is responsible for pjotosynthesis. Scientists theorize that mitochondria were once bateria themselves since they have their own Dna. They incorporated themselves into our cells to help us make energy. The chloroplast uses sunlight to break the hydrogen off the water and use the hydrogen to transfer electrons.

There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiply the series of dilutions together to find the final dilution value. If 6 serial dilutions are performed, each with a dilution of 0.1, what is the cumulative dilution
Answer:
cumulative dilution = 0.000001
Explanation:
A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.
The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:
Cumulative dilution = (F)ⁿ
where:
F = dilution factor = 0.1
n = number of serial dilutions = 6
∴ cumulative dilution = (0.1)⁶ = 0.000001
All of the following are characteristics of cancer cells except
a. No apoptosis
B. Ability to metastatize
C. Angiogenesis
D. Unregulated mitosis
E. Unmutated DNA
Answer:
i think it is c
Explanation:
The option that is not characteristics of cancer cells is E (Unmutated DNA).
Cancer is caused mutations or abnormal activation of cellular genes that control cell growth and cell mitosis.
The characteristics of cells that are cancerous include:
No apoptosis: Apoptosis is programmed death of a normal cell. This doesn't occur in cancer calls as the cells continue to divide giving rise to malignant cells.
Ability to metastatize: This is the ability of cancer cells to migrate to other normal cells and tissues of the body. This so because they are less adhesive to one another.
Angiogenesis: This is the ability of cancer cells to form new blood vessels that supplies blood to it for its nourishment.
Unregulated mitosis: This is the ability of cancer cells to grow without the usual cellular growth limits.
Mutation is the abnormal changes that occur in the deoxyribonucleic acid of a cell.
Cancer cell develop due to mutation of antioncogenes, which are genes present in cells which suppress the activation of oncogenes that lead to cancer.
Therefore, the option that is not a characteristics of cancer cells is E (Unmutated DNA).
