The digestive and excretory systems project explaining macromolecules in the body
Answer:
Our digestive system has the ability to convert macromolecules into micromolecules.
Explanation:
Our digestive system has the ability to convert macromolecules into micromolecules with the help of certain enzymes. Carbohydrate is a macromolecule which is converted into glucose molecule with the help of saliva which is an enzyme present in the mouth, protein is also a macromolecule that is converted into amino acid so that our body cells can absorb it and fats are also macromolecules which can be converted into fatty acids with the help of digestive system. The cells produced waste materials such as carbondioxide gas and nitrogenous material which can be excreted through excretory system such as lungs and urinary bladder.
The DNA molecule could be compared
Answer:
The correct answer is -To a ladder.
Explanation:
Most commonly DNA molecule is considered and compared to a twisted ladder as the structure of DNA can be compared to a ladder. It makes the side of the ladder by an arrangement of alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder.
Nitrogenous bases that are purine and pyrimidine make up the 'rungs' or steps of the ladder and also bind with hydrogen bonds with one other in the rug as two bases make a single rug, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

A) Pressure when the left ventricle contracts
B) Overall blood pressure reading
C) The difference between Volume and Pulse
D) The pressure when the left ventricle relaxes
Answer:
D.
Explanation:
Systolic pressure is the pressure in the arteries when the ventricles are contracting (the 132). Diastolic pressure is the pressure in blood vessels when the ventricles are relaxed (the 78).
That is a high blood pressure, almost Hypertension level

what is the functions of genotypes???
Answer:
The genotype of an organism is its complete set of genetic material, two alleles are inherited for a particular gene by your parents sex gametes (sperm + egg). the genotype determines the persons phenotype eg. polydactyly, your eye colour etc, with a recessive or dominant allele. this can be determined through punnet squares too.
When observing a plant cell under a microscope, what parts do you think would be big enough to see?
Answer:
Explanation:
There are a few key structural differences between plant cells and animal cells.
Below are a few of the main ones:
Plant cells are generally larger than animal cells.
Only animal cells have lysosomes (however, recent, and controversial, research suggests that some plant cells may have lysosomes), and only plant cells have chloroplasts.
While plants cells have a rigid cell wall, animal cells have a thin and flexible plasma membrane.
Plants cells have a large central vacuole and animal cells have many small vacuoles
When observing a plant cell under a microscope, one can see large interlocking rectangular blocks. Around each cell, the cell wall is clearly visible. When stained, the cell wall is somewhat thick and visible. The cytoplasm is also lightly stained, with a darkly stained nucleus at the cell's periphery.
What is a plant cell?A plant cell is a eukaryotic cell with something like a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells.
At the time of observing a plant cell under a microscope, person can see large rectangular blocks as well as cell wall is clearly visible.
When stained, the cell wall is thick and visible. The cytoplasm will also be lightly stained, with stained nucleus at the cell's periphery.
Thus, these structures can be visible under a microscope.

The diagram below shows the ways cells can release energy from food depending on whether oxygen is present.
Respond to the following:
What is the name for the top process (Hint: what is the term for a process that does need oxygen present to occur) ?
What is the name for the bottom process (Hint: what is the term for a process that does not need oxygen present to occur)?
How many ATP are produced at the end of the top process shown?
How many ATP are produced at the end of the bottom process shown?
Answer:
1. Aerobic respiration
2. Anaerobic respiration
3. 36 ATPs
4. 2 ATPs
Explanation:
According to the diagram attached to this question, the process of cellular respiration is described. Based on whether OXYGEN is present or not, cellular respiration can be divided into two:
- Aerobic respiration is the respiration that occurs in the presence of oxygen. As shown in the top process, aerobic respiration starts with glycolysis → krebs cycle → Electron transport chain (ETC). At the end of these three steps, 36 ATP molecules results.
- Anaerobic respiration is the respiration that occurs in the absence of oxygen. As described in the bottom process of the diagram, anaerobic respiration starts with glycolysis and enters alcoholic or lactic acid fermentation depending on which product is formed (alcohol or lactic acid). At the end of the process, only 2 ATP molecules is synthesized.

a. Carbon dioxide is produced in the light independent reactions for use in cellular respiration.
b. Light energy from the sun is absorbed by pigments in the leaf and used to reduce carbon atoms in the production of glucose.
c. Energy, in the form of ATP, is used in the light independent reactions to create glucose.
d. Light energy from the sun is absorbed by pigments in the leaf and used to form glucose to be used by organisms in cellular respiration.
The false statement about photosynthesis is Light energy from the sun is absorbed by pigments in the leaf and used to form glucose to be used by organisms in cellular respiration. The correct option is d.
What is photosynthesis?Photosynthesis is a chemical process by which plants make their food. The process includes sunlight which is trapped by chlorophyll, water, and carbon dioxide which is converted into glucose.
The glucose produced by plants is used by them to carry out their process of theirs, not the organisms in cellular respiration.
Thus, the correct option is d. Light energy from the sun is absorbed by pigments in the leaf and used to create glucose to be used by organisms in cellular respiration.

C. Both A and B are true
D. Neither A nor B are true
Which of the following statements is false? Question 1 options: Bcl2 blocks aggregation of BH123 on the outer mitochondrial membrane thus inhibiting apoptosis. BH123 proteins, like Bax and Bak, are death-promoting members of the Bcl2 family that induce the release of cytochrome c from mitochondria into the cytosol. Bcl2 proteins are part of the extrinsic apoptosis pathway. Some Bcl2 family members promote apoptosis, whereas others inhibit apoptosis.
Answer:
The correct answer is - Bcl2 proteins are part of the extrinsic apoptosis pathway.
Explanation:
The Bcl-2 family group of proteins that are known to either promote or inhibit the process of apoptosis by regulating the mitochondrial membrane potential. Bax and Bak are Bcl-2 proteins, act as pro-apoptotic proteins which oligomerize to result in forming pores in the membrane of the mitochondria.
These pores lead to the release of cytochrome c to the cytoplasm. Bcl-2 protein is an anti-apoptotic protein that inhibits the oligomerization of Bak and Bax.
Describe what happens by the end of anaphase.
a. The chromosomes in the cell become less tightly coiled.
b. The nuclear envelope disappears in the cell.
c. The mitotic spindle of the cell begins to form outside the nucleus.
d. The cell begins to elongate and the two poles have an equivalent collection of chromsomes.
e. The vesicles derived from the Golgi apparatus produce a cell plate at the middle of the cell that eventually forms the new cell wall.
Answer:
d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.
Explanation:
The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.
What occurs during the synthesis stage of the cell cycle?
A. The cell grows, but keeps the same amount of chromosomes.
B. The cell shrinks, but keep the same amount of chromosomes.
C. All DNA is copied, doubling the number of chromosomes.
D. The cell spits, reducing the number of chromosomes by half.
Answer:
its (c)
Explanation:
S phase, or synthesis, is the phase of the cell cycle when DNA packaged into chromosomes is replicated. This event is an essential aspect of the cell cycle because replication allows for each cell created by cell division to have the same genetic make-up.I tried my best.pls mark me as branliest answer plz plz(1) what is active transpot and activesap (2)what happens if transportation does not occur answer me i will mark u as brainlist
1.active transport. The movement of ions or molecules across a cell membrane in the direction opposite that of diffusion, that is, from an area of lower concentration to one of higher concentration. Active transport requires the assistance of a type of protein called a carrier protein, using energy supplied by ATP. SAP Activate is a content-rich and agile methodology for implementation and/or upgrade of SAP solutions across industries and customer environments. It sets out an innovative adoption framework that expedites SAP S/4HANA implementations.
