Choose the correct answer
#1Fish develop more slowly than chickens, mice, and humans.
#2Fish embryos cannot be distinguished from chicken embryos.
#3Mice and humans have no similarities during development
#4Humans are more closely related to mice than they are to chickens or fish
Answer:
#4 Humans are more closely related to mice than they are to chickens or fish.
Explanation:
If you compare the human embryo with the mouse embryo, you can tell they look very similiar, like in the way they curl up and in their eye placement/size. With the other two- fish and chickens- they look extremely different in comparison to the human embryo. The comparisons that i used before (eye placement/size and formation) I'll use as an example. They look nothing similiar to each other, therefore the answer is #4.

Con đường vận chuyển nước vậy ông chất khoáng qua thành tế bào sang bào ở thực vật có đặc điểm gì
Answer:
In plants, minerals and water are transported through the xylem cells from the soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. Thus, there is continuous water movement into the xylem.
Bài giải:
Ở thực vật, các chất khoáng và nước được vận chuyển qua các tế bào xylem từ đất đến lá. Các tế bào xylem của thân, rễ và lá liên kết với nhau tạo thành một kênh dẫn đến tất cả các bộ phận của cây. Do đó, có sự chuyển động liên tục của nước vào xylem.

the allowance for uncollectible accounts is a contra account to
The allowance for uncollectible accounts refers to a company that accepts the risk of giving credits to those who may not pay it back. These debts are written off as uncollectable and are a contra asset on the balance reports.
Uncollectable accounts are also often referred to as doubtful accounts. This implies that the company that is giving the credit accepts the possibility that this entity may not return the money. This results in a loss for the company as is recorded as a contra asset on the balance sheets for the company. Some ways for companies to control this loss are:
Establishing requirements for creditsUsing credit collectors to claim large debtsLimiting amount of loss permitted based on historical and industry records.A contra asset or contra account is an account on a companies balance sheet that decreases the balance of certain assets. Contra derives from Latin and means against. Meaning this is an account that goes against the positive balance of the company, it subtracts from the companies earnings.

Students created note cards comparing characteristics of eukaryotic and prokaryotic cells.
Which set of note cards most accurately compares these cells?
Given what we know about Eukaryotic and Prokaryotic cells, we can confirm that the note card labeled "F" is the one that best compares these two cell types.
Eukaryotic and Prokaryotic cells have many differences to discuss, the ones mentioned in note cards, however, are:
The presence of membranes surrounding organelleThe location of the DNA for each cellProkaryotic cells are cells that lack any organelle or nucleus. This is due to the absence of membranes, which are needed to maintain the structure of the organelle. Due to the lack of membranes and therefore of a nucleus, the DNA of these cells can be found floating in the cytoplasm. Table F is the only one that accurately represents these traits.
Eukaryotic cells, on the other hand, are those that do possess membranes. The presence of membranes allows the eukaryotic cells to have a nucleus that can contain their DNA. This cell type is that of most multicellular organisms, whist the prokaryotic are known most commonly as bacteria. Once again, table F is the one that best represents this data.

during osmosis, the net movement of water molecules will be from areas of __ free energy to areas of __ free energy, or __ energetically.
Osmosis refers to the net movement (diffusion) of water molecules across a semipermeable membrane. This movement occurs in favor of a concentration gradient.
During osmosis, the net movement of water molecules will be from areas of HIGH free energy to areas of LOW free energy, or DOWNHILL energetically.Osmosis involves the movement of water molecules in favor of a concentration gradient, i.e., from an area of high concentration to an area of low concentration.Osmosis is a type of passive mechanism because it does not require energy to move water across the membrane.Learn more in:

if blood calcium levels drop below 8.5 mg/dl which hormone is likely to be activated?
Answer:
Parathyroid Hormone (PTH)
Explanation:
The major function of the parathyroid glands is to maintain the body’s calcium level in both the blood and bones.
There is a narrow range of calcium required for the nervous and muscular systems to function properly. (A normal calcium level in the blood stream ranges from 8.5-10.2 mg/dL ).
When blood calcium levels drop below a certain level, receptors in the parathyroid gland release parathyroid hormone (PTH) in proportion to the amount of calcium that is required by the body. This hormone increases blood calcium levels by stimulating osteoclasts to release calcium by breaking down bone. Osteoclasts are cells in the bones that break down and remodel bone tissue.

A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.

structurally, atp is most like which type of molecule?
Answer:
ATP full name is Adenisin Triphosphate, therefor the molecule would look similar to adensisine, the nucleotide.
Explanation:
Structurally, ATP is most like RNA type of molecule. Therefore, option (A) is correct.
ATP and RNA are nucleic acids, macromolecules made of nucleotides. Cells employ high-energy ATP for energy. Adenosine has three phosphate groups.
RNA also helps gene expression and protein synthesis. Nucleotides comprise ribose sugar, phosphate, and one of four nitrogenous bases (adenine, guanine, cytosine, or uracil).
Ribose sugar and phosphate groups make ATP and RNA structurally similar. Unlike RNA, ATP possesses a high-energy phosphate bond. This additional phosphate bond makes ATP a good energy currency for cells. Therefore, option (A) is correct.
