Answer:
You can use a tea net to separate the Legos and the sand. When you scoop up the sand into the net, the sand will be sifted away because it is smaller than the holes in the tea net. But, the LEGOs are much bigger, so they will remain inside the net.

A man and a woman have recently married , unfortunately they didn't have any children yet. What do you think are the reasons for delayed pregnancy ?
Answer and I will give you brainiliest
Answer:
Late ovulation
explanation
it can delay pregnancy, but that doesn’t mean it won’t happen. It’s entirely possible to conceive when you ovulate later in the cycle; the trick is to be as in tune with your body as possible. By knowing exactly what to look out for, you'll soon be able to tell when you are eventually ovulating.
"Several common reasons for a late period include stress, low body weight, obesity, different hormonal syndromes, birth control, and chronic diseases,"
HELP PLEASE! What is the independent and dependent variable in this experiment and what would be the sample and target population and a generalization.
Will people pick up a dollar bill that is dropped on the floor in the airport during a pandemic?
Answer:
No.
Explanation:
The factors of an experiment is considered as independent because it does not change or not dependent on other while on the other hand, the data is the dependent variable due to its dependency on the treatments. No, people will not pick up a dollar bill which is dropped on the floor in the airport during a pandemic because they can't put their life in danger for a dollar. They knew that life is more important than money.

If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.
3. Which organisms are consumers? (Select all that apply.)
coyote

Does a Hematopathologist work with unicellular or multicellular organisms? Select the BEST answer.
Select one:
a. Multicellular
b. Both equally
c. None
d. Unicellular
Answer:
b
Explanation:
A hematopathologist is a health care professional who works with the unicellular or multicellular organisms, both equally. Thus, the correct option will be B.
Who is a Hematopathologist?Hematopathologists can be referred to as the specially trained healthcare professionals who are responsible for the diagnosis of the diseases related to the different types of blood cells.
Hematopathologists use the specialized tests such as flow cytometry studies and the immunohistochemistry. The hematopathologist uses the results of these tests for the analysis and diagnosis of the infections and diseases of the blood, lymph nodes and the bone marrow.
A hematopathologist works with both the unicellular and multicellular organism equally.
Therefore, the correct option will be option B.

Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.

Answer:
Mutations are only passed on to offspring when they occur in germ cell DNA, which are the cells that create sperm or ova. The other kind of cells, somatic cells, are the rest of the cells in the body, and mutations that occur in these cells do not get passed on to offspring.

In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over
straight hair (a). Paul, who is heterozygous for dimples and curly hair, marries Jane, who
has curly hair but does not have dimples. Jane's mother had straight hair, but her father had
curly hair. Paul and Jane had a child named Peter, who had curly hair but did not have
dimples.
Answer:
1. ddaa
2. DdAa
3. One from each parent
4. False
5. 0.25
6. 0.25
7. 0.25
8. 0.5
Explanation:
The remaining part of the question is
1. What is Jane's genotype?
2. What is Paul’s genotype?
3. Where did Jane get her gene for curly hair? From her mother or father?
4. True or False: Jane's mother was heterozygous for curly hair?
5. What fraction of Paul and Jane's children should have curly hair and dimples?
6. What fraction of their children would have straight hair and no dimples?
7. What fraction should have dimples but not curly hair?
8. What is the probability of getting any offspring with dimples
Solution
1. Genotype of Jane's mother -ddaa
2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa
3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was Aa)
4. False. She was having straight hair
5. Offspring of Paul and Jane
DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)
4 out of 16 offspring will have curly hair and dimples = 0.25
6. ddaa, 4/16 = 0.25
7. Ddaa , 4/16 = 0.25
8. Ddaa, DdAa, 8/16 = 0.5

The artery that will eventually subdivide to form the posterior cerebral arteries is the _____ artery.a) basilarb) external carotidc) maxillaryd) superficial temporale) nternal carotid
Answer:
a) basilar
Explanation:
The basilar artery is an artery whose function is to supply of blood to the brain and central nervous system, thereby transporting oxygenated blood to the brainstem, cerebellum, and occipital lobes for maintaining normal brain function. This artery is 3 to 4 mm in diameter. The basilar artery is formed from the confluence of two vertebral arteries inside the cranium at the level of the medulla. The posterior cerebral arteries are formed by the bifurcation of the basilar artery, and they supply oxygenated blood to the occipital lobes and posteromedial temporal lobes.

Living organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 4 options:
A. sugar
B. minerals
C. hydrogen
D. all of these
Answer:
A.sugar
Explanation:
In the process of phorosynthesis, the plants absorb energey from the sunlight, and with the water they have in the soil and the carbon dioxide they can absorb from the air, they´d produce carbohydrates or sugar and oxygen, in the chemical process of photosynthesys 6 molecules of water are mixed with 6 molecules of carbon dioxide, with addition of solar energy and form 6 molecules of sugar and 6 molecules of oxygen.
