who were the frist people who came to guyana
Answers
Hello,
The first human inhabitants of Guyana probably entered the highlands during the 1st millennium bce. Among the earliest settlers were groups of Arawak, Carib, and possibly Warao (Warrau).The Dutch were the first Europeans to settle modern-day Guyana. The Netherlands had obtained independence from Spain in the late 16th century and by the early 17th century had emerged as a major commercial power, trading with the fledgling English and French colonies in the Lesser Antilles.

What are three tasks that DNA must be able to perform in all organisms? Select three answer choices.
A. It must store genetic information.
B. It must discard foreign genes.
C. It must instruct cells to produce needed molecules.
D. It must copy itself.
E. It must move to locations throughout the cell.
Answers
Answer:
A. It must store genetic information.
C. It must instruct cells to produce needed molecules.
D. It must copy itself.
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the genetic material found in virtually all living organisms. It is the biological molecule that holds the genetic instructions needed for the synthesis of useful products (proteins).
DNA molecule must be able to perform the following tasks in a living organism to be considered the genetic material:
- It must store genetic information: DNA is the storage molecule for genetic information in living cells.
- It must instruct cells to produce needed molecules: DNA must be able to undergo gene expression where it directs the synthesis of the needed molecules like proteins, which it encodes.
- It must copy itself: DNA must be capable of replication i.e. must be able to produce two identical copies of itself.
Answer:
A. It must store genetic information.
C. It must instruct cells to produce needed molecules.
D. It must copy itself.
Why does asexual reproduction result in offspring with identical genetic variation? Use the examples that you studied earlier in this lesson to support your answer.
Answers
Answer:
The reason asexual reproduction results in identical offspring is because the DNA is replicated exactly from the parent to the daughter. One example is bacteria.
Explanation:
Answer:
Sexual reproduction results in offspring 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.

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

Explain how similar and different sexual reproduction in plants and animals is?
Answers
Plant's reproduce via. pollen or seeds, whilst the animals reproduce by, and I quote, "getting on top of each other to have a fun time". Hope that helped
Answer:
Both plants and animals reproduce sexually, producing a male and female gamete, which fuse to form a zygote. However, plants are also able to reproduce asexually, unlike most animals. In sexual reproduction in animals, the two gametes are the spermatozoa and the oocyte, which when fused become the ovum.

how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Answers
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.

Researchers are investigating the use of gene therapy as a treatment option for human genetic disorders, such as cystic fibrosis. When gene therapy is successful, how does it treat the disorder?
A. by activating, or "turning on," one or more genes
B. by deactivating, or "turning off," one or more genes
C. by incorporating a human gene into the genomes of bacteria or other organisms
D. by replacing a faulty gene with a normal gene in the human genome
Answers
Answer:
A
Explanation:
By replacing a faulty gene with a normal gene in the human genome. Therefore, option (D) is correct.
Gene therapy works by inserting a functioning gene into a patient's cells. A viral vector or other delivery method transports the normal gene into target cells.
In cells, the normal gene integrates into the genome and produces the functional protein that was missing or faulty in genetic disorder patients. Gene therapy replaces the damaged gene with a normal gene to repair the genetic origin of the condition and restore normal cell or tissue function.

Grazing is a method of feeding in which herbivores, such as sheep, feed on plants. The intensity in which the herbivores in an ecosystem graze impacts the biodiversity of the plants in that ecosystem, as shown in the graph below.
According to the graph, biodiversity is low during low grazing intensities. This is because only a few species of plants are able to outcompete the others and dominate the ecosystem. As the grazing intensity increases, the biodiversity increases because the dominant plant species are kept in check by the grazers. This allows the weaker competitors to grow. At very high grazing intensities the biodiversity decreases because only plants with adaptations to tolerate the effects of grazing are able to survive.
Which of the following best explains how plant biodiversity would change if all of the grazers were suddenly removed from an ecosystem experiencing high intensity grazing?
A.
Plant biodiversity would likely decrease because every species of plant could grow without limitation after the herbivores were removed.
B.
Plant biodiversity would likely increase because removing one population from an ecosystem would allow more resources for all the others.
C.
Plant biodiversity would likely decrease because a few of the more dominant plant species would outcompete all the others.
D.
Plant biodiversity would likely increase because only a few of the remaining plant species would be able to thrive without the herbivores.

Organisms depend on other organisms and on the nonliving things in an ecosystem to meet their basic needs for food, water and protection. ...
