"Discuss three factors that affect your daily food choices. For each factor with a negative outcome, suggest at least one change you could make in your daily behavior that would turn that negative outcome to a positive outcome.
Answer:
Three factors that affect my daily food choices include:
1. Taste
2. Length of time for preparation
3. Method of preparation.
Explanation:
When making choices for food, I tend to take several factors into consideration. Some of these factors include;
1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.
2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.
To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.
To turn this around, I hope to employ the help of a family member to make the process easier. I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.The purpose breeding experiment is to develop ____________ plants with flowers expressing a new combination of form and shape.

Explanation:
the “good genes hypothesis” proposes that people with physical qualities like averageness, symmetry, sex prototypicality, and youthfulness are more attractive because they are better-quality mates. the “good genes hypothesis” is from which approach to psychology?: 1) evolutionary 2) psychodynamic 3) cognitive 4) biological
The correct answer is 1) Evolutionary
Explanation:
The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.
Explain what the impact of mutations in myosin that disrupt ATP binding would have on the power stroke during muscle contraction. and hydrolysis Skeletal muscle arrangement, ATP binding and correct muscle contractions
Answer:
These cells will be atrophied because muscle contractions can't occur.
Explanation:
In muscle cells, ATP binding causes a conformational change in the structure of myosin, thereby these filaments move to a high-energy configuration. The muscle contraction is caused when this high energy state is amplified in the actin filaments that bind to myosin, in a process dependent on the ATP hydrolysis. The myosin-actin cycle is repeated by binding another ATP molecule on the myosin head, producing the contraction of muscle cells.
Each of the following statements is either true or false.
1. The microscope lens may be cleaned with any soft tissue.
A. True
B. False
2. The microscope should be stored with the ail immersion lens in position over the stage.
A. True
B. False
3. When beginning to focus, use the ssanning objective lens.
A. True
B. False
4. When focusing on high power, always use the coarse adjustment knob to focus.
A. True
B. False
5. A coverslip should always be used with wet mounts.
A. True
B. False
Answer:
1.false.
There are special lense tissues for this which will not scratch the lense so that the focal power will nit be affected. Grit -free lens paper,Kimwipes or Kodak lens are ideal cleaning materials.
2.This is also false. Microscope should be covered with dust cover, and even in the cabinet,It should never be left without am eyepiece.
3.True.
This gives he lowest magnification, which allows for wide view of the specimen in order get the specific spot to focus on.It has magnification power of 10x eyepiece lens.Thus a 4x scanning objective lens therefore gives total magnification of 40x.
4.False,
This will break the objective lens.Fine adjustment knob should be use.This will gives the sharpest focus,using a coarse knob will crack the lens because the working distance for focusing will be too small, and suing this will damage the objective lens,
5.False,only the wet mount should be used.High power and oil lens should not be used as this will reduce the efficiency of the microscope.

How can a forensic palynologist help a crime investigation?
Answer: A forensic palynologist can help a crime investigation because they can examine the pollen in the victim and compare it with the pollen from the suspects by using a comparison microscope to tell if it's a match.
Answer: Well, forensics is the study of the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation. So they have an important role in the judicial system because they study criminal reports and files, Identify and classify crime scene evidence through scientific analysis, and then they have to explore possible links between suspects and criminal activity using the results of chemical and physical analyses. So in a crime scene, they might examine the details that they might notice, like the position of the victim or the objects surrounding the scene, test and analyze them, and then follow the leads they get from that.

After getting their results in, a group of scientists went back and looked at their study. As planned, their experiment consisted of three groups. The first group received a new medicine at a normal dose, the second group received the medicine at half the dose, and the third group received the medicine at twice the dose. Which of the following best describes what went wrong with the scientists’ study?
Answer:
Their experimental design lacks control group
Explanation:
Based on what I read, the scientists don't have a control group as one of the main groups thus they cannot, in scientific sense, say that the medicine is better or worse. You always need a control group receiving no intervention because then we can compare groups and assess the effectiveness of that intervention (in our case if we had control group vs people who received the medicine, we could see if the people who received the medicine had improved condition etc when compared to participants who did not receive anything)
There is no control group in their experimental design. According to what I've read, the scientists don't have a control group as one of the primary groups. Thus, option C is correct.
What is control group?To determine if the treatment is better or worse in a formal scientific sense. You should always have a control group that does not receive any treatment because this allows us.
To compare the groups and evaluate the effectiveness of the intervention. In our case, if we had a control group and participants who did not receive any treatment, we could see if those participants had better health overall.
By focusing on the impact of a single independent variable, a cause-and-effect link can be established.
The independent variable is altered in the treatment group while being held constant in the control group by researchers. The findings of these groups are then compared.
Therefore, no control group in their experimental design.

Why do processes and activities suddenly change the global temperature?
Answer:
hey mate here is your answer
Answer:
Earth's temperature depends on the balance between energy entering and leaving the planet’s system. When incoming energy from the sun is absorbed by the Earth system, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming. When absorbed energy is released back into space, Earth cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including:
Explanation:
Variations in the sun's energy reaching Earth
Changes in the reflectivity of Earth’s atmosphere and surface
Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere
Why do you think these groups have a high risk of osteoporosis
Answer:
lack or low calcium level
Explanation:
when a person has a low calcium intake, these people are susceptible to having osteoporosis as their bodies would be lacking of much needed calcium.
Low calcium intake increases osteoporosis risk. Lifelong calcium deficiency causes osteoporosis. Low calcium consumption causes bone loss, early bone loss, and fractures.
What is osteoporosis?Osteoporosis is a disorder that causes bones to become brittle and more prone to breaking, which increases the risk of fractures. It manifests itself gradually over the course of several years, but the condition is typically not recognized as a problem until a bone breaks as a result of a fall or a sudden impact. A broken wrist is the type of injury that occurs most frequently in people who have osteoporosis.
People who consume inadequate amounts of calcium are at increased risk for developing osteoporosis. The deficiency of calcium over a lifetime is one of the factors that can contribute to the development of osteoporosis. A diet deficient in calcium has been linked to decreased bone density, an accelerated rate of bone loss, and an increased risk of fractures.

II?
A. Solar energy changes ADP into ATP.
B. NADPH turns into NADP+.
C. Glucose forms from carbon dioxide molecules.
O D. Electrons in the third protein gain new energy from light.
Answer:
A. Solar energy changes ADP into ATP.
Explanation:
The phase of the photosynthesis is based on the light that reacts as the pigment molecule absorbs energy from the sunlight and the photons strike the photosystem to initiate the photosynthesis. Energy transports through the electron that pumps hydrogen ions and forms an electrochemical gradient. The ADP is a combination of phosphate to form the ATP in the reaction i.e ADP +energy to ATP plus water. This usually takes place by the storage of high energy to ATP as sugar molecules that are sent phase of photosynthesis.Answer:
A. Solar energy changes ADP into ATP
Explanation:
Photosynthesis is the process in which plants make there own food by utilizing sunlight that converts water and oxygen into carbon dioxide and energy.
There are two systems in photosynthesis: Photosystem II and Photosystem I.
In photosystem II ADP + P is converted into ATP driven by electron gradients formed in the thylakoid membrane.

g A variable trait in corn is the presence or absence of knobs at particular sites on some chromosomes. The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob. If this plant is crossed with a knobless plant, what percentage of the offspring is expected to have only knobless chromosomes
Answer:
50%
Explanation:
The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob.
This means that on a chromosome with two chromatids, the allele present on one chromatid causes the chromatid to possess knob while the other does not making the plant an heterozygous...
If this plant is crossed with a knobless plant, one whose Chromebook is without knobs, we have
II x II
II - 50% with a knobbed chromatid
II - 50% with only knobless chromosomes.
The first to the left is knobbed, thus the percentage of offspring expected to have only knobless chromosomes would be 50%.
Assuming a diallelic gene and complete dominance, the percentage of the offspring that is expected to have only knobless chromosomes is 50%
