Michelle and George are studying the forces and motion of a 0.8-kg low friction cart on a horizontal table. They use a spring scale to exert different amounts of horizontal pulling force on the cart and measure the acceleration of the cart for each pulling force. The measurements of each set of pulling force and acceleration are displayed in the table below. If friction is much weaker than the pulling force, which of the following is the best fit for the missing pulling force in the table?

Answers

Table 1: The horizontal pulling forces (F) and resulting acceleration (a) for the cart.



The cart experiences no motion when there is 0.1 N of horizontal force, so F=0 in this case. When one uses Newton's Second Law to find the acceleration caused by each force, it becomes clear that every row in the chart represents a horizontal force of approximately F=20 N. The best fit for the missing value is F=-30N.

C) An inherited disorder that increases the risk of contracting malaria from mosquitos.
D) A genetic mutation that is inherited from a dominant allele of one parent.

Answers

Answer:

A.

Explanation:

This is when a female reproduces alone

Answer:

Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels.

Explanation:

Based on "Sickle cell anemia is an inherited red blood cell disorder" taken from the text, I would say the correct answer is C, because it says "an inherited disorder" and describes Sickle cell anemia.

The smallest family in the phylum Aves is the bird family.

What is Phylum?

Phylum may be defined as a prevalent taxonomic classification that classifies above class and below kingdom, identical to the division in botany.

The phylum Aves are generally adapted to fly. Hence, it consists of birds or organisms who have the ability to fly in the environment and are classified into this category with a lot of exceptions like bats which belong to mammals.

Therefore, the smallest family in the phylum Aves is the bird family.

Which of the following BEST describes the length of days in Australia when the Earth and sun are positioned as shown in January in the diagram above?


long days.

continual daylight.

short days.

continual darkness.

Answers

Answer:

B is the answer

Explanation:

continual daylight

In the given image it is showing long days. The correct option is A.

What is the relation between day and night?

The Earth orbits the sun once every 365 days and rotates once every 24 hours on its axis.

Day and night are caused by the Earth rotating on its axis rather than by its orbit around the sun.

The term "one day" refers to the time it takes the Earth to rotate once on its axis and includes both day and night time.

A day is roughly the time it takes for the Earth to rotate or for other large astronomical objects to rotate.

The number of daylight hours we have depends on our latitude and how the Earth orbits the sun.

The axis of rotation of the Earth is tilted relative to its orbital plane and always points in the same direction means toward the North Star.

Thus, the correct option is A.

_____ is the process by which energy is stored in inorganic molecules is used to produce carbohydrate food molecules

Answers

Answer:

Chemosynthesis

Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.

that is the answer

Photosynthesis is the process by which energy stored in inorganic molecules is used to produce carbohydrate food molecules.

What is photosynthesis?

Photosynthesis is the primary process by which plants, algae, and some bacteria capture and store energy from the sun.

During photosynthesis, light energy is absorbed by pigment molecules in the chloroplasts of plant cells. This energy is then used to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The glucose produced during photosynthesis is used by the plant as a source of energy and is also stored as a carbohydrate reserve. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.

what route does a red blood cell take to travel from the lung to the kidney

Answers

Answer:

aorta

Explanation:

the red blood cell goes into the kidney trunk and other lower limbs delivering oxygenated blood around the body. They typically last for 120

days before they die.

The blood enters the heart from left atrium. It leaves through the mitral valve into the left ventricle of the heart. The left ventricle then pumps blood through the aortic valve and into the aorta that feeds the rest of the body through a system of blood vessels.

What is function of lungs?

The lungs allow us to breathe and they carry oxygen into body (called  inhalation) and pass carbon dioxide out called exhalation.

Kidney remove toxins and waste, and excess water from the bloodstream, which is carried out of the body in the form of urine. They helped to produce hormones to form red blood cells, and they turn vitamin D into its active form in the body.

What is recombinant DNA ?

Recombinant DNA are the molecule which has been modified to include genes from different origin by the process of either genetic recombination or through laboratory techniques.

In the lab condition,  bacteria can be transformed with recombinant DNA and Genetic recombination occurs via crossing over.

scientists use this recombinant DNA technology created  to add to the genome of another organism which means that scientists can easily add genes from one species into bacteria for the production of the product.

For example, insulin is produced by recombinant DNA technology within bacteria where human insulin gene is inserted into a plasmid, then introduced to a bacterial cell, followed by the production of insulin by bacteria cell.

Explanation:

Denature

Answer:

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.

Active sites and substrate specificity

To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.

In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!

The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens
