Answer:
The force of friction between the two surfaces will increase if the two surfaces are pressed harder against each other. Heavy box will press the floor surface harder as compared to the lighter box. That means the force of friction will be more between the heavier box and surface than between the lighter box and surface. Thus, larger force will be needed to push the heavier box than to push the lighter one.
Which statement best describes the density of the outer planets
Answer:
"The correct statement is, “All the outer planets have low density.”
The outer planets such as Saturn, Jupiter, Neptune, and Uranus are the giant’s planets but in terms of density, they are less due to the gas and jovian.
The densities between the inner and outer circle are different due to the rock-solid.
Explanation:
Enzymes are _______. Enzymes are _______. made of protein permanently changed by the substrate made of protein, are catalysts, and permanently changed by the substrate made of protein and are catalysts are catalysts
Answer:
enzymes are biological catalysts.
Enzymes are catalysts. Therefore, option (4) is the correct option.
Enzymes are biological catalysts made primarily of proteins that accelerate chemical reactions within living organisms. As catalysts, enzymes lower the activation energy required for a reaction to occur, thus speeding up the rate of the reaction without being consumed or permanently changed themselves. Enzymes achieve this by binding to specific reactant molecules, forming enzyme-substrate complexes, which stabilize the transition state and facilitate the breaking and formation of chemical bonds during the reaction.
Once the reaction is complete, the products are released from the enzyme, and the enzyme remains unchanged, ready to catalyze further reactions. Enzymes play a crucial role in metabolism, cellular signaling, and many other physiological processes, enabling life to function effectively. Therefore, option (4) is the correct option.

Scientists base many of their investigations on questions that test accepted theories. Which outcome of an investigation would cause a scientist to ask a different question? A) The observed results are different from the expected results
B) The investigation had many sources of error. C) Another scientist proposed the same theory.
D) The expected results could be explained in different ways.
Answer:
A scientist would ask a different question when he or she founds that the observed results are different from the expected results.
Explanation:
When one expects something and gets something else, then one is having a big enough cause to ask for new questions and initiate a new investigation. Scientific investigation is the process by which the researchers and scientists use a planned approach to answer questions regarding the world around us.How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?
Answer:
A submersible technology designed to operate the submarines underwater.
Explanation:
We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.
Why is it possible for a FPR (formyl-peptide receptor) to detect a formyl peptide in the
absence of a bacterial infection?
Answer:
These receptors were originally identified by their ability to bind N-formyl peptides such as N-formylmethionine produced by the degradation of either bacterial or host cells. Hence formyl peptide receptors are involved in mediating immune cell response to infection.Mark me as brainliest ❤️Which of the following processes releases carbon dioxide as waste?

Each of the following will result in complement activation EXCEPT Group of answer choices TLR binding to PAMP on the microbe. recognition of lipid-carbohydrate molecules on the surface of the microbe. lectin binding to mannose on the surface of the microbe. Antibody binding to antigen. All of these will result in activation of complement.
Answer:
TLR binding to PAMP on the microbe
Explanation:
The complement system is a group of proteins in the blood that enhance immune responses by complementing the ability of antibodies and phagocytic cells to mediate effector responses (e.g., lysis, activation of inflammation, opsonization, solubilization of immune complexes, etc). Complement can be activated through the recognition of microbes by soluble pattern-recognition molecules (i.e., lectin pathway) or antibodies (i.e., classical pathway). The classical pathway requires the formation of antigen-antibody complexes for its activation (it is a specific immune response). On the other hand, Toll-like Receptors (TLRs) are molecular receptors that recognize viral and bacterial products (i.e., pathogen-associated molecular patterns or PAMPs), which is a key defense mechanism from the innate immune system response.
Explain Central Nervous System.
Explanation:
The central nervous system controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
Explanation:
central nervous system is made up of the brain and spinal cord. it receives and integrate impulses from the receptors and then relays them to effector organs. it is the centre of co ordination.

A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood
the child has the blood type of Ab its obvious
Explanation:
only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele
Thus man's genotype: BO or
[tex] { | }^{b} i[/tex]
Woman's genotype : AO or
[tex] { | }^{a} i[/tex]
When
the children can not have O blood
The children cannot have B blood
means the man have BO
[tex] { | }^{b} i[/tex]
and woman have AA
[tex] { | }^{a} { | }^{a} [/tex]
Because
if man have BB, and woman have AA
children can only have AB
if man have BB, and woman have AO
children can only have AB and B

If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).

Describe the change in shape of the lens when a person looks from a near object to a distant object
Answer:
Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
To focus on a near object – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
To focus on a distant object – the lens is pulled thin, this allows the light rays to refract slightly.

The accumulation of glucose 6-phosphate inside a bacterial cell via phosphorylation of glucose is an example of:
Answer:
group translocation
Explanation:
Group translocation is a specialized type of active transport that moves substances across biological cells. In group translocation, substrates are chemically modified during transport across the cell membrane. An example of group translocation is the phosphotransferase system, which is used by bacteria for sugar uptake using phosphoenolpyruvate as the source of energy. This system removes the phosphate groups from phosphoenolpyruvate and adds these groups to glucose molecules in order to form glucose 6-P.
