Hello! My name is Zalgo and I am here to help you out on this amazing day. The way that the younger plant looks the same as the parent plant is because of "Asexual Reproduction". Asexual Reproduction is how plants can reproduce. Considering it is a plant and not a human asexual means that plants reproduce without the need of "sexual intercourse".

Which of the following should be used to make a precise measurement of liquid volume
Answers
A graduated cylinder is the correct tool for making precise measurements of liquid volume, with marked scales for accuracy and the ability to measure at different increments.
To make a precise measurement of liquid volume, the appropriate tool to use is a graduated cylinder. Graduated cylinders are specifically designed to measure liquid volumes with a high degree of accuracy. They are marked with a graduated scale that allows users to read the volume of liquid inside the cylinder. Option D
These marks indicate specific volumes, which can vary in measurement units such as milliliters (mL) or centiliters (cL). For instance, if you're measuring a small volume of liquid, a 100-mL graduated cylinder can measure with an accuracy of "+/-1 mL", allowing for quite precise measurements. When using a graduated cylinder, it's important to measure at eye level and use the lowest point of the liquid's meniscus to obtain an accurate reading.
draw the structure of DNA nucleotide with adenine as nitrogenous base
Answers
Answer:
A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.
Explanation:
A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.
A DNA nucleotide with adenine consists of a phosphate group, deoxyribose sugar, and adenine base connected to the deoxyribose.
A DNA nucleotide with adenine as the nitrogenous base consists of three main components: a phosphate group, a deoxyribose sugar, and adenine as the nitrogenous base.
Firstly, there is a phosphate group which is a phosphorus atom bound to four oxygen atoms.
This group provides the backbone's negative charge to the DNA molecule and contributes to its structural stability.
Secondly, we have the deoxyribose sugar, a five-carbon sugar. It is a pentose sugar, meaning it has five carbon atoms. The carbons are labeled from 1' to 5' (prime).
The phosphate group is attached to the 5' carbon of one deoxyribose sugar and the 3' carbon of the preceding deoxyribose sugar, forming the sugar-phosphate backbone of the DNA strand.
Lastly, adenine is one of the four nitrogenous bases in DNA and is classified as a purine. It is attached to the 1' carbon of the deoxyribose sugar.
Adenine forms hydrogen bonds with thymine (T) in complementary base pairing in a DNA molecule. The nitrogenous base adenine has a specific structure, including a double ring.
In summary, the DNA nucleotide with adenine includes a phosphate group forming the backbone, a deoxyribose sugar providing the structure, and adenine as the nitrogenous base attached to the deoxyribose sugar at the 1' carbon.
This structure is fundamental to the building blocks of the DNA molecule, allowing for the storage and transmission of genetic information.

Answers
Answer:
B: Alveoli.
Explanation:
ANSWER:
The correct option is B: Alveoli. Gas exchange of "carbon dioxide and oxygen" takes place in the "alveoli" of the lungs.
EXPLANATION:
Alveoli are present in the alveolar sacs located at the end of respiratory bronchioles. Alveoli have thin walls and look like bubbles in the sacs. These also are in "direct contact" with the blood capillaries. This contact ensures that "oxygen" is released into the blood capillaries by the alveoli directly.Which disease is typically linked to both genetics and lifestyle choices?

The disease that is typically linked to both genetics and lifestyle choices is diabetes. Unlike sickle cell anemia, which is a genetic disorder caused by mutations in just one gene, diabetes is a multifactorial disorder with both genetic and lifestyle components. Conditions such as heart disease, obesity, and diabetes do not have a single genetic cause; they are likely associated with the effects of multiple genes in combination with lifestyle and environmental factors.

fluids?
(a) Kidneys (b) Skin (c) Liver (a) Lungs (e) Ovary
Answers
The answer is a Kidneys
Answer:
(A).Kidneys is the correct option.
Explanation:
Kidneys are part of the urinary system, its function is to maintain fluid balance and to regulate and remove the minerals from the blood.
Kidneys control the water potential of the tissue fluids by maintaining the accurate amount of water and it removes the metabolic wastes, which help to maintain the composition of fluids present in the body.
The human body has two kidneys, which control the water potential, excess water is excreted through urine.
Blood through the renal artery is transported to the kidney, where it gets filtered, kidney reabsorbs the useful materials like glucose,water and ions. Once it is purified,it is transfer to the circulatory system and waste material such as salts, water and urea excreted in the form of urine which control the water potential.
Urine is produced by the kidney, by performing this process Kidneys control the water potential of the tissue fluids.

what happens in meiosis during telophase 2
Answers
Answer:
Option (B).
Explanation:
Meiosis may be defined as a type of cell division in which four daughter cells are produced from the single parent cell. The resulting daughter cells contain half number of chromosomes as compared with the parent cell. This type of division is also known as reduction division.
During telophase 2, the nuclear envelope forms, chromosome moves towards opposite poles and the cell follows cytokineses and result in the formation of four daughter cells.
Thus, the correct answer is option (B).
In meiosis during telophase 2 a total of four daughter cells forms. The correct option is B.
The following events occur during telophase 2 of meiosis, the last phase of meiosis II:
The chromosomes reach the cell's opposing poles. Each pole has a haploid pair of chromosomes at this phase.Nuclear envelopes begin to rebuild around the chromosomes that have been split.The spindle fibres separate.Cytokinesis occurs, resulting in cytoplasm division and the development of two distinct daughter cells.It is vital to note that four daughter cells are generated at the end of meiosis II, each having a haploid pair of chromosomes.
As a result of separate assortment and genetic recombination during meiosis I and meiosis II, these daughter cells are genetically different from one another and from the parent cell.
Thus, the correct option is B.

The energy from the photosynthesis equation is transferred into sugars, where it is stored in the chemical bonds of glucose and used by organisms in ecosystems.
The energy shown in the equation of photosynthesis is transferred into sugars. During photosynthesis, plants convert the radiant energy from sunlight into stored chemical energy. This energy is captured through a series of reactions that result in the production of glucose and oxygen. The energy is stored in the chemical bonds of glucose, a type of sugar, which organisms use to perform various functions such as movement, growth, and reproduction. This stored energy can then enter ecosystems and continually be transferred from one organism to another through the food chain.
