Answer: Wind Energy
Explanation: Wind power is considered more efficient than solar because they use less energy, release less carbon dioxide and produce more energy overall.
Wind energy runs 24 hour a day since it doesn't depend on sunlight to create energy unlike solar energy panels.
Studies of topsoil erosion on Iowa farmland shows that as much as 50 metric tons are lost per hectare during winter and spring rains. This loss is due to the loss of millimeters of soil from across the entire surface of the fields. Which type of erosion would this be?
Answer:
The type of erosion described in the question is called Water Erosion.
Explanation:
Note that the erosion is caused by winter and spring rains.
Water Erosion can happen when raindrops disintegrate the aggregates of the topsoil. The fragments collect into the soil pores and create a coagulating action which makes it difficult for the water to penetrate the soil. The rainwater having increasingly accumulated on the surface flows off along with the topsoil.
This type of erosion can be further aggravated if:
the rainfall is very heavy;the terrain has a steep gradient thus increasing the velocity of runoffthe soil type has a lower capacity to erosionCheers!
explain absorption of food
Key Points
Digested food is able to pass into the blood vessels in the wall of the small intestine through the process of diffusion.
The inner wall, or mucosa, of the small intestine is covered in wrinkles or folds called plicae circulares that project microscopic finger-like pieces of tissue called villi, which in turn have finger-like projections known as microvilli.
The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients.
Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
Key Terms
villi: Tiny, finger-like projections that protrude from the epithelial lining of the intestinal wall.
plicae circulares: These circular folds (known as the valves of Kerckring or the valvulae conniventes) are large, valvular flaps that project into the lumen of the bowel.
diffusion: The act of diffusing or dispersing something, or the property of being diffused or dispersed; dispersion.The Small Intestine
The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.Digested nutrients pass into the blood vessels in the wall of the intestine through a process of diffusion. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.
Structurally, the mucosa is covered in wrinkles or folds called plicae circulares—these are permanent features in the wall of the organ. They are distinct from the rugae, which are non-permanent features that allow for distention and contraction.
From the plicae circulares project microscopic finger-like pieces of tissue called villi (Latin for shaggy hair). The individual epithelial cells also have finger-like projections known as microvilli. The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients.
Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface. The epithelial cells of the villi transport nutrients from the lumen of the intestine into these capillaries ( amino acids and carbohydrates) and lacteals (lipids).
The absorbed substances are transported via the blood vessels to different organs of the body where they are used to build complex substances, such as the proteins required by our body. The food that remains undigested and unabsorbed passes into the large intestine.
Chylomicrons A. are synthesized in intestinal epithelial cells. B. enter capillaries in the small intestine. C. help emulsify fats. D. are a rich source of carbohydrate. E. are synthesized in the lumen of the small intestines.
Answer:
E
Explanation:
I don't know. How Supposed to help you
Chylomicrons are synthesized in intestinal epithelial cells to transport long-chain triglycerides to the tissues. Therefore, option (A) is correct.
What are chylomicrons?Chylomicrons are lipoprotein particles made up of triglycerides, phospholipids, cholesterol, and proteins. They are also known as extremely low-density lipoproteins. They move dietary lipids from the intestines to other bodily parts.
Chylomicrons deliver lipids ingested from the gut to the adipose, cardiac, and skeletal muscle tissues, where their triglyceride components are digested by the action of the lipoprotein lipase, releasing the free fatty acids that may then be absorbed by the tissues.

In response to increased levels of aldosterone, the kidneys produce In response to increased levels of aldosterone, the kidneys produce urine with a lower concentration of sodium ions. urine with a higher concentration of sodium ions. urine with less glucose. a larger volume of urine. urine with a lower concentration of potassium ions.
Answer:
The correct answer is urine with a lower concentration of sodium ions.
Explanation:
A hormone produced in the cortex or the outer section of the adrenal glands, which are located above the kidneys is known as aldosterone. The hormone plays an essential function in regulating the blood pressure primarily by functioning on the organs like colon and kidney to enhance the reabsorption of sodium or salt into the bloodstream and to enhance the concentration of potassium excreted in the urine.
Along with sodium, the hormone also works to reabsorb more concentration of water, which further increases the volume of blood and thus the blood pressure. Therefore, with the increase in the levels of aldosterone, the kidneys generate urine with a lower concentration of sodium ions.
In response to increased levels of aldosterone, the kidneys produce urine with a higher concentration of sodium ions. Therefore, option B is correct.
Aldosterone is a hormone produced by the adrenal glands, specifically in the zona glomerulosa of the adrenal cortex. It plays a crucial role in regulating sodium and potassium levels in the body.
When aldosterone levels increase, such as in response to low blood sodium levels or stimulation by the hormone angiotensin II. Then, it acts on the cells of the distal convoluted tubules and collecting ducts in the kidneys.

a. sunlight driving photosynthesis in plants
b. herbivores feeding on plants
C. predators feeding on herbivores
d. none of the above
Answer:
d. none of the above
Explanation:
Energy, which refers to the ability to do work, can exist in different forms. The process of changing energy from one form to another is called TRANSFORMATION OF ENERGY. In an ecosystem, all organisms require energy in order to perform their life processes. They acquire these energy in different forms and convert it to a usable form by their cells (chemical energy) in ATP.
For example, solar energy in Sunlight is used by plants to drive their photosynthetic process and change it to chemical energy in glucose. Also, predators and herbivores feeding on herbivores and plants respectively converts one form of energy to another. Hence, all options are examples of energy transformation. None of the above is the correct answer.
Answer:
I think the correct answer is d ,

:)An organism is _______ for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s _______, or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are _______.
Mendel’s law of _______ governs which allele is expressed in an individual.
Respond to the following based on your reading.
In the previous section, you learned that the allele for brown eyes (B) is dominant, and blue (b) and green eyes (g) are recessive, while green eyes are dominant over blue eyes. What eye color would someone with the following genotypes exhibit? (a) BB, (b) Bb, (c) gb, (d) Bg, (e) bb.
Discuss the law of segregation and explain why each organism has two copies of the gene for each trait expressed.
What type of experiments did Mendel conduct, and what did he want to find out about the heritability of the seven traits he chose to study?
Answer:
1. Purebred (N.B: the exact word is considered a foul word)
2. Phenotype
3. Linked
4. Segregation
5) (a) BB- Brown eyes
(b) Bb- brown eyes
(c) gb- green eyes
(d) Bg- brown eyes
(e) bb- blue eyes
The other questions are explained below
Explanation:
1. A purebred organism is that which possess two copies of the same alleles in its genotype. An allele is a contrasting form of a gene. If the two alleles are the same, the organism is said to be purebred.
2. Phenotype of an organism is the observable characteristics of the organism. It is determined by the organism's genotype in interaction with its environment.
3. Mendel's law of independent assortment states that the alleles of a gene will separate into gametes independently of another gene unless the genes are linked. Linked genes are genes that are too close to each other on a chromosome and hence, do not sort independently. They're rather inherited together.
4. Mendel’s law of Segregation governs which allele is expressed in an individual. According to this law, an organism will express the allele it randomly receives from each parent. If an organism receives two different alleles, it will express the allele that is dominant. In other words, an organism will only express the recessive trait if it receives two recessive alleles from both parents.
5. a) BB- Brown eyes because the organism is purebred for the dominant (brown) allele
(b) Bb- brown eyes because the brown allele (B) will mask the expression of blue allele (b) and express itself.
(c) gb- green eyes because the allele for green eyes (g) is dominant over the allele for blue eyes.
(d) Bg- brown eyes because the brown allele (B) is dominant over the allele for green eyes (g), hence, it will mask its expression
(e) bb- blue eyes because the organism is purebred for the blue allele i.e. same recessive (blue) alleles in the gene.
6. The law of segregation as proposed by Mendel states that the alleles of a gene will separate into gametes during gamete formation (meiosis). This is done in such a way that each gamete contains only one allele of each gene. Hence, an organisms will contain two copies of a gene because they receive each copy (allele) from each parent during fusion of their gametes.
7. Mendel conducted an hybridization experiment i.e. a cross involving two individuals that possess different traits. He did this in order to find out how different traits/characteristics in organisms were transferred from one generation to another. Mendel chose the pea plant for his experiment because they could easily be manipulated for self and cross pollination. Mendel studied seven (7) different traits or characteristics in pea plants including height, seed shape, seed color, flower color etc.
