name the stimulus, control control center, and the receptor when ABA is released. Please I need answers thanks!
Answer
ABA
Explanation:
It is believed that this mechanism, in situations of hydric stress, is controlled mainly by abscisic acid, a plant hormone known as ABA. This hormone binds to receptors in the membrane of the guard cells and promotes the entry of calcium ions (CA2+), which function as messengers when opening ionic channels. When these channels are opened, the chlorine(Cl-) and malate2- ions pass from the inside of the cell to the wall and open the K+ channels, causing the exit of this ion as well. This process causes the water to come out and the stomach closure occurs. When the ABA is released from the receiver, the ions that came out of the cytoplasm, together with the water, return to the inside of the cell, making it turgid. At this moment, the stomach opens.
Therefore, it is perceived that the ABA causes the stomatum to close, thus guaranteeing water savings. In environments with water stress, this mechanism guarantees the survival of the plant.
In addition to water stress, several factors directly affect the opening and closing of the ostyolus, such as the concentration of carbon dioxide, light, temperature and water loss. It is also worth mentioning that the stomata also open and close at circadian rhythms, that is, according to daily rhythms.

The illustration shows a sequence of bases on one strand of a DNA molecule. Use the illustration below to answer the next three questions.
How many amino acids are coded for by the sequence on side A of this DNA strand?
What is the order of bases on side B, from left to right?
If G replaced A as the first base on side A, what would the order of bases be on side B of this DNA strand?
The diagram is lacking but the number of amino acids can be calculated by having into account that three nucleotides produce a codon. It is the genetic code.
What is the genetic code?The genetic code makes reference to the linear order of nucleotide bases in a given DNA strand.
This linear order is fundamental to produce a particular mRNA, which is used as a template during translation.
When occurs a substitution (mutation) of a nucleotide base for another in a DNA strand, then the genetic code can be used to determine the amino acid that will be added to this new codon.

Answer:
There is no answer to that.
Explanation:
Chlorophyll is located in the chloroplast, and it is a crucial component in green plants for photosynthesis.Cells walls are present in plant cells only.Large central vacuoles are part of plant cells, too.None of the options are correct.
Vacuoles are also present in both the animal cells and plant cells. Therefore, option (A) is correct.
What is a plant cell?A plant cell is a type of cell that is found in plants. It is similar to an animal cell in many ways, but there are also some important differences. Like animal cells, plant cells have a cell membrane, cytoplasm, and genetic material (DNA) contained in a nucleus. However, plant cells also have some unique features that are specific to plants.
One key feature of plant cells is the presence of a cell wall. The cell wall is a rigid structure that surrounds the cell membrane and provides support and protection for the cell. It is made up of cellulose fibers and other structural proteins.
Plant cells also contain organelles called chloroplasts, which are responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain pigments called chlorophyll, which absorb sunlight and use it to convert carbon dioxide and water into glucose (a sugar) and oxygen.
Plant cells also contain other specialized organelles, such as mitochondria, which are responsible for producing energy for the cell, and vacuoles, which are large, membrane-bound structures that store water and other substances.
Overall, plant cells are important for a variety of functions in plants, including providing structural support, producing energy, and performing photosynthesis.

Does a kangaroo have a dorsal nerve cord notochord?.
Kangaroos have a dorsal nerve cord notochord. It is a feature of mammals.
What is Dorsal nerve cord notochord?The dorsal hollow nerve cord is a hollow cord dorsal which is present to the notochord. Notochord is generally formed from a part of the ectoderm which rolls, forming the hollow tube. It is important for distinguishing the chordates from other animal phyla, such as the Annelids and Arthropods, which have solid, ventral tubes.
The notochord is a flexible rod-like structure which is made up of mesodermal cells which serve as the primary longitudinal structural element of the chordates. Notochord is found in the early embryos of vertebrates and serves as an organizing role in the development of the nervous system.

how can you survive a very cold winter
Answer:
Prepare! Follow our winter survival kit checklist for tips on proper clothing, winter car kits, home supplies, and more.
Hypothermia and frostbite are the real dangers. Even in 50 F temperatures, you’re at risk of losing too much core and limb heat.
Protect your body heat. Protect it, trap it, and treat it like the precious resource it is.
Keep covered. Wind and exposure are the enemy. Exposed skin accelerates heat loss, especially through wind.
Dress in layers. The air trapped between each layer holds your body heat, like your own personal hot tub. Plus, layers give you better control over regulating body heat so you can avoid dangerous sweating.
Avoid sweating and stay dry. Besides moisture loss, sweating is bad because water on your skin makes you colder. That’s why we sweat to begin with — it’s the body’s air conditioning system.
Snow is an insulator. Don’t be afraid to use it for shelter.
Avoid eating snow. You lose a lot of core heat by melting snow inside your body. Melt it outside your body instead.
Alcohol does not warm you. Sorry, Russia!
Hydrate. Severe cold can be just as dangerous as severe heat. Stay hydrated.
Don’t travel unless you have to. Conserve energy. Stay where you’re most likely to be found. Especially if you’re in a nasty storm where navigation and shelter is difficult.

A company wants to test a new dog food that is supposed to help overweight dogs lose weight. 50 dogs were chosen to try the new food and 50 other dogs were chosen to continue their normal diets. After one month, the dogs are checked to see if they lost any weight. What is the Dependent Variable?
Answer:
The dependent variable is the weight of the dogs
Explanation:
The dependent variable is the variable that is been tested during the course of an experiment. The dependent variable will usually produce different unpredictable "values" which will form the essence of the experiment. Also, the dependent variable is usually dependent/relies on the independent variable.
From this description, the dependent variable is the weight of the dogs as this is the variable that is been tested.
The compound synthesized during photosynthesis is-
A. H2O (water)
B. C6H12O6 (Glucose)
C. CO2
D. Light (solar) energy
Answer:
D
Explanation:
The term photosynthesis means literally “synthesis using light.” Photosynthetic organisms use solar energy to synthesize carbon compounds that cannot be formed without the input of energy. More specifically, light energy drives the synthesis of carbohydrates from carbon dioxide and water with the generation of oxygen.
i hope this helps :)
The compound synthesized during photosynthesis is C₆H₁₂O₆ (Glucose). Option B is correct.
During photosynthesis, plants use energy from sunlight to convert carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆) and oxygen (O₂). This process takes place in the chloroplasts of plant cells, specifically in the chlorophyll-containing structures called thylakoids.
Photosynthesis is a complex process in which plants use sunlight energy to convert carbon dioxide and water into glucose and oxygen. Glucose is an essential compound synthesized during photosynthesis, providing energy for plant growth and other metabolic processes.

Chromosomes replicate to make a new copy of DNA
Chromosomes line up at the middle of the cell
Chromosomes are moved to either pole of the cell
Chromosomes pair up as homologous chromosomes
After the nucleus breaks down and chromosomes condense in prophase Chromosomes line up at the middle of the cell
In Prophase the chromosomes gets shorten and thicken. After metaphase chromosomes line up in the middle of the cell. During Anaphase chromatids break apart at the centromere and move to opposite poles. Mitosis ends at telophase were two nuclei formed after nuclear envelopes wraps around each group of chromosomes.
When Mitosis is complete, the cell has two section of 46 chromosomes, each enclosed with their own nuclear membrane. The cell in the ends splits by the process of cytokinesis and create two identical clones of 46 chromosomes .
