Question 1) Discuss the types of trace elements in organic compounds? ( Will Mark Brainliest).
Answers
Answer:The trace elements are those organic compounds that are needed for the growth and maintenance of plants from the soil in small amounts.
Explanation:
The types of trace element which are also called non-essential elements include:
Copper: This takes part in chlorophyll and seed production.
Boron: This takes part in the maintenance of structural and functional integrity of biological membranes.
Molybdenum: This is required for the synthesis and activity of the enzyme nitrate reductase used in the synthesis of amino acids in plant cells.
Manganese: This sustains the metabolic roles within different plant cell compartments; and
Zinc: This is responsible for the synthesis of certain proteins.
Which phrase correctly defines a gene?

a segment of DNA
a segment of a protein
a part of the cell membrane
Answers
Answer:
A segment of DNA
Explanation:
Genes are parts of DNA
A gene is a segment of the DNA (deoxyribonucleic acid). DNA is the genetic material of the cell which contains the information for the development of different characteristics in an organism. Thus, the correct option is B.
What is a Gene?
A gene is the basic unit of heredity in an organism. It can also be defined as the molecular gene which is a sequence of nucleotides in the DNA molecule that is transcribed to produce a functional RNA which synthesizes a protein. There are two main types of molecular genes which include protein-coding genes and the noncoding genes.
Protein-coding genes or exons are the regions in the DNA which encodes for the synthesis of protein and the non-coding genes or introns are the segments of the DNA which does not code for any protein and thus are spliced in the post-transcriptional mechanism.
Therefore, the correct option is B.

Which of the following statements regarding digestion and absorption of carbohydrates is TRUE? Lactose intolerance results from an insufficiency of the enzyme amylase. Digestible polysaccharides are broken down into the monosaccharides glucose, galactose, and fructose, which can be absorbed. Sucrose is the main form of carbohydrate that can be absorbed by active transport across the intestinal epithelium. Carbohydrate digestion begins in the stomach. Cellulose from plants is a polymer of glucose that can be easily digested and absorbed by the human GI tract.
Answers
Answer:
CARBOHYDRATE DIGESTION AND ABSORPTION
For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.
The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).
The major disaccharidases, located in the brush border of the intestinal lumen, are
•
Maltase—hydrolyzes maltose
•
Sucrase-isomaltase—hydrolyzes sucrose and isomaltose
•
Lactase—hydrolyzes lactose
Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.
HISTOLOGY
Brush Border Dynamics
The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.

In a population of cattle, the average body fat percentage is 10.5%. You select parents with an average body weight percentage of 20.8%. The offspring they produce have an average body weight percentage of 17.6%. Based on these data, what is the narrow-sense heritability of this trait
Answers
Heritability in the narrow sense -h²- refers to the proportion of the phenotypic variability that is influenced by genetic factors. In the exposed example, the narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7
-----------------------------
Before answering the question, let us first review a few concepts.
The selection differential, SD, is calculated by getting the difference between the mean value of the desired trait in the population (X₀) and the mean value of the same trait expressed by parents, (Xs). So,SD = Xs - X₀
Heritability in the narrow sense -h²- is the measure of the genetic component to which additive genetic variance contributes.It referes to the proportion of the phenotypic variability that is influenced by genetic factors.
The heritability might be used to determine how the population will respond to the selection done, R.
h² = R/SD
The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h² with the selection differential, SD.R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₁ - X₀
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
Population average body fat ⇒ 10.5% ⇒ X₀ Selected parents average body weight ⇒ 20.8% ⇒ XsOffspring average body weight ⇒ 17.6% ⇒ X₁We ned to get the narrow-sense heritability of this trait, h².
h² = R/SD
R = X₁ - X₀ = 17.6% - 10.5% = 7.1%SD = Xs - X₀ = 20.8% - 10.5% = 10.3%
h² = R/SD = 7.1% / 10.3% = 0.689 ≅ 0.7
The narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7

How do bogs keep themselves cool
Answers
Answer: Like humans, dogs need to keep themselves cool to protect their bodies. They do sweat, but not in the same way. They only have sweat glands only on the paw pads and nose leather. Since they are covered with fur, it is more challenging to keep their bodies cool.
After your dog runs around, you will notice that he begins to pant heavily. Dogs rely on panting to keep their bodies cool. Panting causes the evaporation of water from the nasal cavity, tongue, throat and lungs, which helps lower their body temperature.
They also experience the same dilation in blood vessels as humans, which brings blood to the surface of the skin, allowing the air in the environment to cool them.
Any dog is at risk for heat-related problems, especially in warm, humid weather. Our brachycephalic friends are at a much greater risk than their long-nosed counterparts. Large breeds with thick coats, such as Bernese Mountain dogs or Pyrenees are also more prone. Dogs with pre-existing heart conditions or respiratory issues are also more likely to be overcome by the heat.
When these dogs pant to try and cool themselves, they have to work harder to do so. This only raises their body temperature even higher, making it worse instead of better.

The cytoplasm side of a neuron is negatively charged while the outside of the neuron is also negatively charged. c.) The cytoplasm side of a neuron is more negative than the outside of the neuron. d.) The cytoplasm side of a neuron is more positive than the outside of the neuron.
Answers
Given what we know about the nervous system and resting neurons, we can confirm the cytoplasm side of a resting neuron is more negative than the outside of the neuron.
What is a neuron?Neurons are specialized cells that make up the nervous system in the body. Their primary function is to act as messengers, delivering information in the form of electrical impulses and neurotransmitters. These neurons work using rapid shifts in membrane potentials.In order to do this, the starting value or resting point of the membrane is negatively charged.Therefore, we can confirm that since neurons function using shifts in membrane potentials, the starting point or resting form of a neuron has a negatively charged membrane, meaning that the cytoplasm side of a resting neuron is more negative than the outside of the neuron.
