Which explanation best describes why sexually reproducing organisms have greater genetic
variation than asexually reproducing organisms?
Helppp
Answer:
think of it this way lol
Explanation:
In asexual reproduction, you are essentially producing clones of the parent. There is no genetic variation between parent and offspring - think of mitosis.
In sexual reproduction, you have several chances for genetic variation. The first occurs in meiosis 1, when homologous pairs line up and crossing over occurs. Then in meiosis 2, different combinations of chromosomes (some from mother, some from father) could end up in the gamete cells. Finally, when the gametes (egg and sperm/spore) come together in fertilization, that represents a brand new combination of chromosomes, and therefore alleles, than either of the parents had.
Which option correctly classifies the plant in the following scenario?
The stem of a non-coniferous young plant is cut horizontally. Inside, the vascular bundles are arranged in rings around a central core.
dicot
gymnosperm
cotyledon
monocot
Answer:
dicot
Explanation:
because when the plant is cut horizontally, the central becomes dicot
6. Which of the following is a technique used by scientists to date fossils?
A fossilization scale
B. absolute dating
C. carbon imaging
D. plaster casting
Answer:
B. absolute dating
Explanation:
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.
Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events such as fossils by scientists.

D. the joining together of exons to form the gene
Answer:
C. RNA polymerase binding to a region near the gene, called the promoter
What is the role of chlorophyll is photosynthesis?
A. Carries high-energy electrons from the thylakoids to the stoma.
B. Converts carbon dioxide into glucose.
C. Absorbs energy from sunlight.
Answer:
Chlorophyll's job is to obsorb sunlight into the plant to be able to use the process of photosynthesis! Answer is C
2. Which fruit provides an analogy as to the thickness of the
crust of the earth?
Answer:
The orange is analogous to the Earth in having a relatively dense centre (mantle/core) and a much less dense skin (crust).
Answer:
A good anology is an oarnge because it has a thin/semi hard "crust" while the inside is much softer and bigger
what is the difference between DNA and RNA
Answer:
DNA is double-stranded, RNA is single-stranded. DNA has the base Thymine, RNA replaces it with Uracil. DNA has deoxyribose sugar, RNA has ribose sugar.

What are the characteristics of life that all living things have in common?
Answer:
Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
According to the evidence scientists have gathered, whales and hippos are more closely related than whales and fish. Describe the types of evidence a scientist uses to infer whether two species such as whales and hippos share a common ancestor.
The type of evidence that scientists use to infer ancestry includes morphological, molecular, and embryological evidence, and the fossil record.
What is evolution?
Evolution can be used to describe descendence from a common ancestor of two or more species.
The presence of homo-logous structures is indicative of common ancestry between different species.
These homo-logous structures can be observed during the embryo stage of organisms and the observation of the fossil record.

Most genetic diseases are caused by recessive alleles. Why? (1 point)
A) Recessive alleles are never expressed, so they confer no disadvantage to survival.
B) Dominant alleles that cause disease are removed from the population over time, but recessive alleles can
persist indefinitely in the population.
C) Genetic diseases occur only in heterozygous gene pairings.
D) The statement is untrue. Genetic diseases are most commonly caused by dominant alleles

what is a DNA
what does DNA stand for
Answer:
Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Deoxyribonucleic acid
Explanation:
hope this helps...
Answer:
DNA is short for Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In other words, whenever organisms reproduce, a portion of their DNA is passed along to their offspring.

Grassland ecosystems in Texas have evolved to depend on periodic fires to return nutrients to the soil and encourage plant reproduction. Humans have prevented fires in many of these grassland areas, resulting in plant and animal communities with little diversity. Wildlife biologists often recommend purposefully starting fires called prescribed burns, which are monitored and controlled, in grassland ecosystems every 3 to 4 years. These biologists observe greater diversity in plant and animal life in the years following a prescribed burn. What natural processes are the biologists attempting to imitate
Answer:
Succession
Explanation:
The biologists were attempting to imitate succession.
Succession refers to a gradual change to the structure and species composition of a community over a period of time.
A newly colonized environment such as a bare rock forms a community is said to be in primary succession. Thereafter, the structure and composition of the community keep changing until a relatively stable community, otherwise known as climax community, is established.
Secondary succession happens when a disturbed community tries to regain its original dynamics in terms of species composition and structure. A climax community is often less diverse than a community that is still in active succession.
Hence, the biologists were attempting to imitate succession by burning/disturning a relatively stable, less diverse climax community of grassland in order to realize a more diverse community that will undergo secondary succession.
Answer:
Succession

HELP PLEASE ! Which statement best describes the result of meiosis?
A. It produces body cells.
B. It causes alleles to go bad.
C. It prevents genetic problems.
D. It produces gametes/ sex cells.
Answer:
D. It produces gametes / sex cells.
Explanation:
Meiosis is a reductions division, so the source of the sex cells will produce the gametes, undergoing meiosis. The gametes will have half the number of chromosomes in a human body (23).
