HELP PLS Using the picture below, which wave would have a higher pitch.

Answer:

Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land - meandering - or going around objects such as hills or large rocks.

Explanation:

Hope this helps!

Answer:

A river is created when water moves from higher elevation to lower elevation. It usually goes downhill, and can join with other rivers. The river ends when it flows into an ocean.

Answer:

Answer: Four sperm cells.  

Explanation:

Explanation: Meiosis is is a cell division process that generates four haploid cells (gametes) from a single diploid germline cell.

In the drosophila fruit fly, four haploid sperm cells are produced from a single original parent cell. The germ cells undergo meiosis to form gametes. Thus, the correct option is C.

Meiosis is the reductional division through which four daughter cells are produced from a single parent cell. The gametes are produced from meiosis. The gametes produced from a diploid cell are haploid in the number of chromosomes in cells. Both male and female gametes undergo fertilization to form diploid zygote.

Meiosis is divided into two parts- Meiosis I and Meiosis II. Both the parts comprises of four phases- Prophase, Metaphase, Anaphase, and Telophase. The chromatids undergo crossing over with non-sister chromatids to form recombination in cells.

Therefore, the correct option is C.

#SPJ6

Answer: No, the daughter will be a carrier only.

Explanation: Hemophilia is a sex-linked recessive disorder. The recessive gene is carried on the X chromossome. Males have only one X chromossome, while females have 2. So, for a male individual to have hemophilia, it only needs the recessive gene to be on the X chromossome. In a female, the disorder is expressed when both X chromossomes has the recessive gene.

In the Parent Chromossomes picture shown, the father's X chromossome doesn't have the gene for hemophilia and the mother is heterozygous for the trait, i.e., she carries the recessive gene.

A daughter will inherit an X chromossome from the father and an X chromossome from the mother.

In this family, the daughter will inherit the X with dominant gene H for the father and has a possibility of inheriting another dominant gene H or recessive gene h from the mother.

For the daughter to be hemophiliac, she has to inherit 2 recessive genes. Since in either case she won't, she only inherits 1 recessive gene, the daughter will be a carrier for the trait, not have the disease.

Explanation:

Answer:

1.its microscopic and it is the building block to every organism

2. unicellular means 1 cell or type of cell

3. Multicellular means multiple cells or types of cells

4. prokaryotic, eukaryotic?

Answer:

They contain symbiotic rhizobia bacteria within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil

Answer:

75% purple and 25% white

Explanation:

When a punnett square is drawn to predict the phenotypes of the pea plants offspring:

- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)

- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)

This is true

Sexual reproduction results in offsrping with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.

Explanation:

When connected together by series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on other interactions (dashed lines) between its amino acid side chains.

Amino acids are the subunits or monomers of proteins i.e. proteins are made up of amino acids.

WHAT ARE PROTEINS?

Hence, amino acids are monomeric units of protein molecules.

Answer:

decreases a plant’s weight

Explanation:

Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.

Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.

Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.

Hence, the correct answer is "decreases a plant’s weight".

#CarryOnLearning

In this activity, students learn about the Human Genome Project. They do an interactive Web activity which simulates the process scientists use to determine the sequence of chromosomal DNA bases. Then they learn how two teams of scientists raced to decode the human genome. Next they explore a stretch of sequenced DNA on the Web to learn about the function of different sections of DNA code. They learn how knowledge of the human genome is being applied to medicine. They also learn about genetic variation among humans and between humans and other species. Finally, they assess what they have learned about the Human Genome Project by playing a game of Jeopardy.

Objectives

Learn about the purpose and work of the Human Genome Project

Describe the process of sequencing human DNA

Understand the functions of different stretches of code on a chromosome

Recognize the similarity in the genetic code among humans and between humans and other species

Learn how the Human Genome Project can contribute to curing diseases
