describe the effects that enzymes can have on substrates
Answer:
Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.
Explanation:
Hope this helps.
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process

A lot of your personality comes from ______________________ rather than your DNA.
Answer:
Inheritance
Explanation:
Many believe that personality traits can come from how you are treated when you are a child while that can play a part in a personality trait that's not the full truth. Personality traits are inherited from your parents so if your father is stubborn but not your mother there's a 50% chance that the child may be stubborn like his or her father.

7. Pick two of Earth's spheres (biosphere, atmosphere, geosphere, hydrosphere), and draw a model showing how these two systems interact. Your model should show components of these systems, at least one way these components interact, and inputs and outputs that move from one system to another.
Answer:
alright, the answer is biosphere
Explanation:
The earth sphere that is the biosphere is a product of the interaction of atmosphere, lithosphere, and hydrosphere. Together they are called as the geosphere.
All these spheres interact with one another and their interaction leads to life on earth. The atmosphere consists of the most essential gases known to maintain temperature and sustain life on earth such as oxygen. The other component knows as the hydrosphere has water which when interacts with air through the processes of evaporation, condensation, and precipitation all driven by the solar mechanisms.Thus the air and water cycle interaction leads to the input and output of energy in the ecosystem.

Make a prediction of this: A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The scientists pointed out that because beets grow underground, they continue to grow in freezing conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter. To test this hypothesis, the scientists froze equal volumes of water on two separate plates. They spread an extract of beet roots on one plate of ice and sprinkled an equal amount of salt over the other plate. After keeping both plates at 0°C (the temperature at which water freezes) for a period of time, they measured the amount of melted water on each plate. Their results showed that the plate treated with beet extract contained more liquid water than the plate treated with salt.
Answer:
extract of beet roots could be used as antifreeze for water systems
Explanation:
In science, a prediction can be defined as a plausible conjecture that is subsequently proved (or rejected) using the scientific method. In other words, a prediction is the expected result obtained if the hypothesis is true. Scientists make predictions based on falsifiable hypotheses which can be tested through experimental and/or observational procedures. In this case, it could be predicted that the extract of beet roots could be used as anti-freeze for water systems in cold climates.

A scientist claims that he has protected animal test subjects from a newly mutated virus using an experimental vaccine.The experimental vaccine was injected into five animal test subjects. The scientist also injected a placebo vaccine into five other animal test subjects.One month later, all of the test subjects were exposed to the mutated virus. The subjects that received the vaccination showed no sign of the disease and blood tests confirmed the presence of antibodies against the disease, but the subjects given the placebo developed symptoms of this condition.Why did one group have a placebo injected before being exposed to the virus?A) They were part of the experimental groupB) They would be protected from the diseaseC) They would be exposed to a weaker form of the virusD) They were part of the control group
Answer:
The correct answer is option D. they were part of the control group.
Explanation:
A control group is a group of subjects different from the other test subject as they did not get the independent variable's effect on them and separated from the rest of the experiment. This group of subjects is used to rule out any other explanation of the effect of the independent variable.
In this experiment, subjects that received a placebo injection are the control group as they did not expose to the mutated virus and there are the presence of antibodies in the blood.
During weeks 17-20, quickening occurs, which is when the
A. fetus' sense of hearing is developing at a rapid pace
B. mother can hear the fetus' heartbeat with headphones
C. fetus' heart rate increases to 150 beats per minute
D. mother is able to feel the fetus move inside her womb
A: D. mother is able to feel the fetus move inside her womb
E: ED20 CA-Psychology
During weeks 17-20, quickening occurs, mother is able to feel the fetus move inside her womb. The correct option is D.
What is gestation period?It is measured in weeks, beginning with the first day of the woman's last menstrual cycle and ending with the current date.
A normal pregnancy can last between 38 and 42 weeks. Premature babies would be those born prior to actually 37 weeks. Postmature infants are those born after 42 weeks.
It is common in mammals, but it also occurs in some non-mammals. Mammals can have one or more gestations at the same time during pregnancy, as in a multiple birth.
Pregnancy is calculated from the first day of the woman's last period, rather than the date of conception, which usually occurs two weeks later.
Quickening occurs during weeks 17-20, and the mother can feel the fetus move inside her womb.
Thus, the correct option is D.

Deer need food and water to survive. What are food and water for the deer population?
carrying capacity
limiting factors
population growth
scarce resources
Deer need food and water to survive, and these resources are essential for the deer population to thrive.
Where water can be found?Water can be found in streams, lakes, and ponds, and food for deer populations can include grass, leaves, twigs, fruits, and nuts. Carrying capacity, limiting variables, population increase, and scarce resources can all have an impact on the availability of these resources.
The greatest number of deer that a particular ecosystem can support is known as carrying capacity. If the deer population surpasses the carrying capacity, resources will become scarce and the population will begin to drop.
This is determined by the amount of food and water available in the area. Disease, predation, and human hunting are limiting variables that can also have an impact on the deer population's size and the amount of food and water they have access to.
Population growth is also an important factor, as when the population grows too quickly, the resources may become scarce and the deer will struggle to survive. Finally, scarce resources can also affect the deer population, as when resources are not readily available, the deer will have to compete for food and water, leading to a decrease in their population.

In pedigree B, how can unaffected parents have an affected child?
Answer:
The unaffected mother, who is marrying in, does not carry an allele for the disease; so the affected child inherits an allele only from the affected father. No child could be affected by a single autosomal recessive allele, or X-linked recessive allele, so the trait is dominant
Answer:
The childs mother could be a carrier without knowing it which would create the couple to have a child thats affected.

LOVE LETTER: You are writing a love letter to water. Using the meanings of at least
6 properties of water (cohesion, adhesion, density, pH, moderates temperature, hydrogen
bonding, polarity, solubility), to explain to water why you love it so much. Ex: "Your
neutral pH is so much more attractive than orange juice's sour & acidic pH"
Answer:
Dear water,
I love you, You are highly special to me as you are attracted towards you own molecules(cohesion) and others as well(adhesion). Your density is so compatible that its used as standard for almost all reactions. You are neither acidic nor basic and you hold a PH of 7. You can also be used as temperature moderators as you have the highest specific heat capacity. You hold special bonds with selected molecules and form hydrogen bonding, Polarity of you molecules makes you bend just like ammonia and your solubility is exceptional as you are considered a good solvent these qualities of your makes me love you even more.
