Explanation:
Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

When you feel cold, there are sensors in your skin that tell the brain you need to warm up. The brain sends messages, by way of nerves, to the muscles in your body causing them to contract and relax very quickly resulting in a shiver. The movement of the muscles during a shiver generates heat which can be used to warm up the surrounding tissues. Which characteristic(s) of life is being represented during this action?
A) respond to stimuli
B) maintain homeostasis
C) growth and adaptation
D) respond to stimuli and maintain homeostasis

How do you get 0 blood type?
Answer:
You cannot change your blood type. You are born with what you are biologically given and it is permanent.
Answer:
What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child. Each of their kids has around a 1 in 8 chance of having O negative blood. This is possible because both O and Rh- are something called recessive traits.

45 / 10000 Word Limit Question 2 (b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
Answer:
Hydrophobic tails interact among themselves, while polar (hydrophilic) heads interact with water
Explanation:
In the first place, the polar heads of the phospholipids localized on the membrane surface interact with surrounding water molecules that also surround other cell phospholipids. Second, the non-polar tails of the phospholipids from one cell interact with molecules that repel water in the other cell phospholipid. Consequently, it forms a bilayer structure composed of two sheets of phospholipids where hydrophobic tails are arranged on the inside of the membrane, thereby allowing the interaction tail-to-tail among different cell membranes, while the polar heads of the disrupted phospholipid membranes interact together with the surrounding water.

Compare transitional aquatic ecosystems. Identify two types in the organizer below and describe the environments each type combines. 9th grade Biology
Answer:
The correct answer is -
wetlands - land and water
estuaries - freshwater and salt water
Explanation:
There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.
Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.

Answer:I need some points,, I hope y’all can understand
Explanation:
The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.
What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.

In the question “How does pineapple consumption affect the number of digestive bacteria?”, pineapple consumption is
A) the control group B) independent Variable
C) dependent variable D) experimental group
Answer:
For the approach of how does pineapple consumption affect the number of digestive bacteria?, pineapple consumption is the independent variable (option B).
Explanation:
The formulation of a hypothesis is not complete without the existence of the independent and dependent variables, the main variables from the research point of view.
The independent variable is one whose change or modification is capable of impacting the dependent variable, which is one that can be quantified or measured.
According to the approach, if somebody want to know how the consumption of pineapple influences the number of digestive bacteria, the independent variable is the consumption of pineapple, which can be controlled and modified, while the characteristic that is under the influence of this variable is the amount of bacteria, so that the latter is the dependent variable.
The other options do not apply because:
The experimental (D) and control (A) groups refer to the population in which the study is conducted. The dependent variable (C), in this case, is the amount of digestive bacteria.Photosynthesis/CR definition
Answer:
Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
How do you know if something is alive? Describe some of the characteristics of living things.
Answer:
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
Answer:
To be alive organisms have to include all of the following:
- Made up of a cell or cells
- Has DNA
- Can reproduce
- Responds to the environment
- Grows and develops
- Exchanges energy
- Evolves
Explanation:
Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.

Howard Gardener's theory of multiple intelligences suggests that there are eight different types of intelligence instead of a single generalized one. Bodily-kinesthetic intelligence is one of them that is the ability to skilfullly use the body or its parts.
Natasha's experience tells that she may be high on this specific kind of intelligence as athletes like her and dancers like her are high on bodily-kinesthetic intelligence.
The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?
a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients

Answer:
Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated
