A fir tree has leaves that stay green all year long. These trees produce cones, and their reproductive structures can be dispersed by the wind. To which group does the fir tree belong? nonvascular plants angiosperms gymnosperms seedless plants

Answers

Answer:

gymnosperms

Explanation:

Gymnosperms are a diverse group of plant, second to angiosperms, that both belong to the HIGHER PLANTS category. Gymnosperms are characterized by their ability to bear seeds on naked structures called CONES. They do not produce flowers or fruits as opposed to gymnosperms.

They are usually evergreen i.e. do not shed their leaves all season long. According to this question describing a fir tree, which has leaves that stay green all year long and produce cones, that allows for wind dispersal, the fir tree is a GYMNOSPERM.

Explain why just protecting a species like the grizzly bear with a law may not be enough to conserve this species?

Answers

Answer:

When laws are made to protect a species, it is made to stop human interference. Often natural factors also are the reason for a species decline, some of these factors may include, habitat change, climate change and may also be a disease going through the species. In order to truly save a species you would have to isolate them in an area and make sure they are all healthy and the habitat does not change. The only issue with that is, they could lose some of their natural instincts such as hunting or being scared of humans. So a law may not be enough to save a species because there may also be many natural factors interfering with a species survival.

Explanation:

In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar. This sugar can then be consumed by other organisms to be used as building blocks for other molecules, such as proteins and fats, or it can be transformed into other forms of energy, such as kinetic energy, when the organism moves. Which of the following statements is supported by the above information? A. Energy can change forms, but only one kind of matter exists. B. Matter and energy must always remain in the same form and location. C. Matter and energy can change forms and locations in ecosystems.

Answers

Answer:

Matter and energy can change forms and locations in ecosystems.

Explanation:

Matter and energy can change forms and locations in ecosystems.

In the given information, light energy changed into chemical energy and then into kinetic energy, and sugar changed into proteins and fats as it moved from the Sun to the plant and then to other organisms.

It is important to note that although matter and energy can change forms and locations in an ecosystem, the total amount of matter and energy must always remain the same according to the laws of conservation of matter and energy.

Which is most likely a physical change?

cutting a substance into four pieces
burning a substance into ash and smoke
reacting a substance chemically to form a new substance
combining a substance with water to make rust

Answers

Given what we know, we can confirm that a physical change would be slicing the substance into four pieces, option A is correct.

Why is slicing the substance a physical change?

This has to do with the fact that this option focuses on the physical characteristics of the substance, such as the shape and size, whereas the other options would in one way or another affect its chemical nature, by reacting with fire, chemicals, or water respectively.

Therefore, we can confirm that a physical change would be slicing the substance into four pieces.

Describe the niche of the giraffe.

Answers

A niche is the role an animal plays in its environment. A giraffes niche would be their long necks. With their necks they can reach up higher and eat where no other animals can eat. Giraffes don't have to compete with other animals for their food so they live peacefully with other animals.

Answer:

A niche is the part of an animal that plays important role in its environment.

A giraffes niche would be their long necks. With their necks they can stand up higher and eat where no other animals can reach to eat.

Giraffes don't have to contend with other animals for their food so they survive harmoniously with other animals.

Their necks are instrumental in much of this niche, determining what the giraffes eat and what they see.

The elongated necks of giraffes support them consume leaves, blossoms and fruit that are higher than most grazing animals can touch; only elephants can compete for food at the equivalent level

The presence or absence of freckles is determined by one gene. The allele for freckles (F) is dominant and the allele for the absence of freckles (f) is recessive. A couple has several children. All of the children have freckles because their parents' genotypes can only produce children with freckles. Which of these are most likely the genotypes of the two parents?

Answers

Answer:

There are no options to this question, however, the question can be answered. The answer is:

FF and FF/Ff

Explanation:

This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.

According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.

What part of a microwave oven protects humans against radiation?
1. glass doors
2. plastic outer covering
3. metal shields
4. magnetrons

Answers

Answer:

metal shields

Explanation:

I took the quiz and exam

Humans are shielded from radiation by metal parts of a microwave oven. So, the correct option is C.

What is Microwave oven?

A microwave oven, often known as a microwave or electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food. A microwave oven is indeed a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.

Water, lipids, carbohydrates, and a few other molecules absorb the microwaves, which causes their vibrations to produce heat. Hence, cooking time is significantly shortened because the heating takes place inside the food rather than warming the air around it. Metal components of a microwave oven protect people from radiation.

Therefore, the correct option is C.

How does variation lead to natural selection?

Answers

Answer:

Natural selection can not create variations it can only eliminate the existing variations that are not as well adapted to the changing environment as others. Natural selection acts like a racket. Natural selection preserves variations that are best suited to environment. Variations are known to create changes within a species. These changes are also known as adaptive evolution or micro evolution.

The variations required to create changes from one species to another species have never been empirically observed. These changes are known more correctly as Darwinian evolution or macro evolution.

Variations is the driving force in evolution or change. Natural selection can only act on existing variations. So for evolution of any kind to occur there must be variations.

Five little boys have been raped and killed in the past three weeks. All of them have died due to strangulation with a rope. There were no other person's fingerprints or body fluids on the bodies. The boys all lived in an area of Memorial Drive in Dekalb County. The police fear the killer will attack again. What specialist is needed to find or identify the killer and predict where he might strike next? Why?

Answers

Answer:

Forensic biologist

Explanation:

The specialist needed to find or identify the killer would be a forensic biologist. A forensic biologist uses trace samples or evidence in identifying victims and/or suspects and generally supporting criminal investigations with the aid of scientific techniques. In the case described in the question, there are other samples (aside from body fluids and fingerprints) that can be obtained from the crime scene; for example, in the case of a struggle with the killer, some of the boys could have pulled hair strands from the killer. The root of these hair-strand can be subjected to DNA analysis to identify the killer. There is also the possibility of having one of the boys scratching some skin cells from the killer; these could also be useful in DNA analysis.

The forensic biologist could also determine when and where the actual death of the boys took place, this information could be vital for the law enforcement in predicting where the killer might strike.
