Answers

Motion energy refers to the energy related to an object's movement. When an object is in motion, it possesses kinetic energy, which is a form of motion energy.

How to explain the energy

The matching will be:

motion energy = energy related to an object's movement

chemical energy = stored energy related to positions of atoms within molecules

thermal energy = energy of motion of particles in a substance

nuclear energy = energy released when a nucleus splits or combines

gravitational potential energy = energy related to height

sound energy = energy generated by vibration of a string

Chemical energy is stored energy that is related to the positions of atoms within molecules. It is the energy that can be released or absorbed during a chemical reaction. When chemical bonds are formed or broken, energy is either released (exothermic reaction) or absorbed (endothermic reaction) in the process.

Which of the statements describes how marine fish maintain osmotic balance?

A) They maintain body fluid solute concentrations that are higher than that of the surrounding water.

B) Chloride cells in the gills actively pump chloride ions into the body.

C) They tend to gain water through osmosis.

D) They drink water to replenish water supplies.

E) They are osmoregulators.

Answers

B) Chloride cells in the gills actively pump chloride ions into the body is the statement that describes how marine fish maintain osmotic balance.

Marine fish live in a hypertonic environment, which means that the solute concentration of seawater is higher than that of their body fluids. To maintain osmotic balance, marine fish have specialized cells called chloride cells in their gills that actively pump chloride ions into the body. This process helps the fish to excrete excess salts and maintain a balance of solutes in their body fluids.

Option A is incorrect because marine fish actually maintain body fluid solute concentrations that are lower than that of the surrounding water.

Option C is also incorrect because marine fish tend to lose water through osmosis, not gain it.

Option D is incorrect because marine fish do not drink water as a means of replenishing their water supply.

Option E is also incorrect because marine fish are not osmoregulators; they are actually osmoconformers, meaning that their body fluids match the salinity of the surrounding seawater.

What are Bald eagle homologous structures

Answers

The wing of a bald eagle is homologous to the wing of a penguin. Homologous structures are structures that are of similar evolutionary origin.

How do we explain?

Homologous structures are  described as anatomical features found in different species that have a common evolutionary origin. These structures may have different functions in different organisms, but they share a similar underlying structure and can be traced back to a common ancestor.

The wing of a bald eagle and the wing of a penguin are considered homologous structures because they both evolved from a common ancestral structure, even though they serve different purposes  which is flight in the case of the bald eagle and swimming in the case of the penguin.

You are running an experiment to study seed germination and accidentally left a dish of seeds covered with a little water in a totally dark room. When you return a few days later, you notice that the seeds have sprouted long roots and long shoots. What was the source of most of the matter that makes up these roots and shoots?A. oxygen in the airB. carbon dioxide in the airC. water in the dishD. glucose in the seed

Answers

Answer:

D. glucose in the seed

Explanation:

Plants generally make their food through the process of photosynthesis in the presence of sunlight by utilizing carbon-dioxide and water and produces oxygen and carbohydrate.

But due to the absence of sunlight, plant will be unable to use carbon dioxide and water for photosynthesis and oxygen is a by-product.

So the reason of seed germination is the presence of glucose in the seed. Seeds generally germinate through the process of inhibition, that require uptake of water. Glucose works as energy source in humans and plants as well. sugar or glucose allow the seed to utilize the water and help foster its growth.

Hence, the correct option is D. glucose in the seed.

Which of the following statements is true regarding the absorptive and postabsorptive states? Check all that apply The absorptive state only lasts for approximately 30 minutes after a meal. During the absorptive state nutrients may be used immediately to meet energy demands. Glycogenolysis is most likely utilized to meet energy demands during the postabsorptive state, Blood glucose drops dramatically during the absorptive state. Gluconeogenesis most likely occurs at least 4 hours after the last meal.

Answers

The statements that are true regarding absorptive and post-absorptive are -

option (2): During the absorptive state nutrients may be used immediately to meet energy demands

option (3): Glycogenolysis is most likely utilized to meet energy demands during the post-absorptive state

option (5): Gluconeogenesis most likely occurs at least 4 hours after the last meal.

What is  absorptive and post-absorptive state?

Absorptive stage = fed state and post absorptive stage = fasting state.

The absorptive state is the time when ingested nutrients enter the circulation and part of these nutrients meet the body's energy needs while the rest is stored. The post-absorptive stage is the time when the GI system is depleted of nutrients and the body must rely on stored energy.

Option 2: Nutrients can be utilized directly to fulfill energy demands during the absorptive period.

Explanation: Taking a glucose solution while exercising provides athletes with instant energy. As glucose begins to be absorbed from the mouth.

Option 3: Glycogenolysis is most likely used to supply energy requirements during the post-absorption period.

Explanation: During the post-absorptive phase, the liver glycogen begins to break down and create glucose for the body's energy source.

Option 5: Gluconeogenesis happens at least four hours after the last meal.

Explanation: Our bodies require extra energy after around four hours of absorption. The gluconeogenesis process then begins.

Whereas,

Option 1: The absorptive condition lasts 4 hours, not 30 minutes.

Option 4: Blood glucose levels rise sharply during the absorptive period and do not fall.

3.3 The inheritance of fur colour in cats is sex-linked. The tortoise-shell colour of cats is a combination of black and orange fur.

HINT: The sex chromosomes/gonosomes in cats are the same as in humans. 3.3.1 Use the symbols X³. X and Y to represent a genetic cross of the mating stated above. Also indicate the proportion of the F₁ phenotypes. Explain why the male kittens can never have the tortoise-shell colour. 3.3.3 Explain why the female kittens can have the tortoise-shell colour. 3.3.2 (7) (2) (2) (11)

Answers

Answer:

The inheritance of fur color in cats is indeed sex-linked. The tortoise-shell color is a combination of black and orange fur. The allele for black fur is represented by X³ and the allele for orange fur is represented by Xº. When a female cat with a tortoise-shell color mates with an orange male cat, the genetic cross can be represented as follows:

Xº Y

X³ X³Xº X³Y

Xº XºXº XºY

The proportion of the F₁ phenotypes would be 1:1 for females (50% tortoise-shell and 50% orange) and 1:1 for males (50% black and 50% orange).

Male kittens can never have the tortoise-shell color because they only inherit one X chromosome from their mother. Since the alleles for black and orange fur are both located on the X chromosome, male kittens can only inherit one or the other, but not both.

Female kittens can have the tortoise-shell color because they inherit one X chromosome from each parent. If they inherit the X³ allele from one parent and the Xº allele from the other parent, they will have both black and orange fur, resulting in a tortoise-shell color.

Some experts attribute the increase in ADHD diagnoses to an increased awareness of the disorder, while others attribute the increase to ______ diagnoses.

Answers

Answer:

incorrect

Explanation:

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. ADHD is characterized by different behaviors that include one or more of the following symptoms: inattention (poor concentration), impulsivity (interrupting behavior) and hyperactivity (state abnormally active). It has been reported that DHD diagnoses in children between 4 and 17 years of age dramatically increased from 6 percent (6%) during the period 1997-1998 to 10 percent (10%) during the period 2015-2016. Although the causes of this increase have not been established, the American Psychiatric Association (APA) indicates that the increase might be due to the increased access of communities historically relegated to receive care and decreased stigma to be diagnosed with ADHD. Other possible causes range from chemical factors to unhealthy habits during pregnancy (e.g., smoking, substance abuse, poor nutrition). On the other hand, it has also been proposed that this increase may be as a result that ​ADHD is often misdiagnosed and confused with other conditions (e.g., bipolar disorder, autism, kids being kids, etc).
