A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
He should conduct tests using computer models to determine the safety impact.

1. One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic
information is passed among those types of molecules. Include the results of the processes of
transcription and translation
Answer:
Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines.

Which paragraph in the section "Speciation" BEST supports the idea that animals can adapt in ways that allow multiple species to survive together in a common area?
Question 2 options:
A) Sometimes, an organism develops an adaptation or set of adaptations that create an entirely new species. This process is known as speciation.
B) The wide variety of marsupials in Oceania is an example of how organisms adapt to an isolated habitat. Marsupials, mammals that carry their young in pouches, arrived in Oceania before the land split with Asia. Placental mammals, animals that carry their young in the mother's womb, came to dominate every other continent, but not Oceania.
C) Koalas, for instance, adapted to feed on eucalyptus trees, which are native to Australia. The extinct Tasmanian tiger was a carnivorous marsupial and adapted to the niche filled by big cats like tigers on other continents. Marsupials in Oceania are an example of adaptive radiation, a type of speciation in which species develop to fill a variety of empty ecological niches.
D) The cichlid fish found in many of Africa's lakes exhibit another type of speciation, sympatric speciation. Sympatric speciation is the opposite of physical isolation. It happens when species share the same habitat. Adaptations have allowed hundreds of varieties of cichlids to live in Lake Malawi. Each species of cichlid has a unique, specialized diet: One type of cichlid may eat only insects, another may eat only algae, another may feed only on other fish.
Answer:
I will say C
Explanation:
Sorry if I am wrong.
Paragraph in the section "Speciation," BEST supports the idea that the Koalas, for instance, are adapted to feed on eucalyptus trees, which are native to Australia, and that this is present in the option C.
What is the significance of the koalas?They have various importance, such as being culturally significant in Australia, bringing economic benefits to the area, being important for scientific research and understanding marsupials, and so on. They are considered a vulnerable species due to habitat destruction, but they play an important role in the ecosystem as they are herbivores and help control the growth of eucalyptus trees.
As a result, paragraph in the section "Speciation," BEST supports the idea that the Koalas, for instance, are adapted to feed on eucalyptus trees, which are native to Australia, and that this is present in the option C.

Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell. They contain all the genetic information of an organism. Humans have 46 pairs of chromosomes, with half from each parent. Which of the following best describes why the offspring will receive only half of the parents' chromosomes?
A)Chromosomes assort independently, and crossing-over occurs.
B)Gametes contain homologous pairs from the mother and father.
C)Diploid eukaryotic cells become haploid before fertilization.
D)The cell cycle stops, allowing for extra haploid cells to be made.
Answer:
C
Explanation:
I am pretty sure answer is C.
Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.
What is the function of the chromosome in meiosis?The chromosomes present in the parent cell duplicate in the S phase of the cell cycle, and in the meiosis phase of the cell cycle, the daughter chromatids segregate and form four haploid cells from the parent cell. The child or offspring is the result of the fertilization of the sperm and the ovum, and the zygote is formed from the process that develops into the offspring, and the zygote has half the genetic contents of the paternal and maternal parents. In this way the chromosomes separate in the meiosis.
Hence, Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.

The scientific name of an organism is made up of what two group names?
Answer:
Genus species
Explanation:
Scientists use a special naming system for organisms. It is made up of two words.
The first word is the genus of the organism and the second word is the species of the organism.
The first word, which is the genus, is always capitalized, but the second is not. Both words are italicized if possible, but if you are handwriting the scientific names, an underline suffices.
An example of a scientific name for a house cat is:

Plants are predominantly autotrophic, with some hetertrophic exceptions.
OTrue
O False
Answer:
True
Explanation:
Autotrophic means making your own food, providing it without consuming other organisms. Heterotrophic is the opposite: think of the prefixes auto- meaning self and hetero- meaning different.
Most plants use photosynthesis to get energy from the sun; that's their own source, no eating other organisms necessary. Examples are grasses, flowers, trees.. most mainstream plants. There are a few exceptions, like something nasty like a Venus flytrap.
Explore: Use the Gizmo to create three more carbon paths, each starting and ending in the atmosphere. Label each location with A for atmosphere, B for biosphere, G for geosphere, or H for hydrosphere. (You can also use P for the anthroposphere if you like, or just include it in the biosphere.)
Carbon-dioxide gas is essential for maintaining life on earth.
Carbon-dioxide present in the atmosphere comes from breathing of animals and volcanic eruption. this carbon-dioxide absorb by the plants (biosphere) in the process of photosynthesis. This carbon-dioxide is incorporated in the soil (geosphere) with the dead bodies of plants and animals and decomposition of these bodies occurs and carbon-dioxide gas again releases in the atmosphere. Carbon-dioxide gas is also dissolved in the water bodies where it is required by the plants for photosynthesis and made food for the marine animals.
