. Gymnosperms are a group of seed plants that produce___
1.seeds, pollen and fruit
2.no flowers or fruit
3.no seeds or pollen
4.flowers and fruit
Answer:
2 is the right answer
Explanation:
they do not produce fruit or flowers think of a pine treee of a spruce tree
Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.
What are gymnosperms?A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
The Coniferophyta, Cycadophyta, Gingkophyta, and Gnetophyta are the four primary phyla that makeup gymnosperms. Conifers, which have needle-like leaves and thrive in arid, cold climates, are the most common gymnosperm.
Some examples of gymnosperms are ginkgo, pine, melinjo. sago palm, cedars, and spruces. Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.

they don't move.
Explanation:
all these statements are true.
give two reasons that a particular molecule may be unable to cross the plasma membrane
Answer:
The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.
Every cell has 3 billion DNA base pairs. How does this long strand of DNA fit into a nucleus?

How does cell division relate to the process of asexual reproduction ?
Answer:
sexual reproduction occurs by cell division during mitosis to produce two or more genetically identical offspring. Sexual reproduction occurs by the release of haploid gametes (e.g., sperm and egg cells) that fuse to produce a zygote with genetic characteristics contributed by both of the parent organisms.

You design an experiment to test the hypothesis that consuming caffeine increases a person's chances of developing a headache. Participants in the experimental group will be told to drink 8 ounces of caffeinated soda in the morning once a day for 10 days, and to abstain from drinking any other caffeinated beverages or soda. Which of the following is an appropriate control group for your experiment?
a) A group that drinks 8 ounces of decaffeinated hot coffee (no caffeine) in the morning once a day for 10 days and abstains from drinking any other caffeinated beverages or soda
b) A group that drinks 8 ounces of caffeinated soda once a day for 10 days in addition to their normal beverage habits
c) A group that drinks 8 ounces of decaffeinated soda (no caffeine) in the morning once a day for 10 days and abstains from drinking any other O caffeinated beverages or soda.
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Answer:
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Explanation:
In an experiment, two groups exist as follows: experimental group and control group. Experimental group is the group that receives the experimental treatment (independent variable) while the CONTROL GROUP is the group that does not receive the experimental treatment.
In this experiment, the experimental treatment is the CAFFEINATED SODA (contains caffeine). Hence, the appropriate control group for this experiment will be the group that does not drink any soda (whether caffeinated or decaffeinated) or other caffeinated beverages for 10 days.
The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are designated male. Individuals with XO (only one X chromosome) are designated female. Identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the offspring. An XY parent with a round nose and a XX parent with a round nose have an offspring with Klinefelter Syndrome (genotype XXY) with a pointed nose.
Answer:
Explanation:
in this case female parent XX is hetrozygous for round nose. when a cross between round nose father XY and hetrozygous round nose mother takes place and suddenly a chromosomal nondisjuction occurs, the chromosomes carrying genes for pointed tip nose come togather in a gamete and a gamete (egg) with XX chromosomes is appeared having 24 chromosomes instead of 23. when this gamete fertilizes with a sperm having normal 23 chromosomes and only carry Y chromosomes, a pointed nose klienfelter syndrome case will appear.

A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

Moles are mammals that live underground and eat worms. The moles are adapted to use their sense of smell to locate their food. Which environmental change would MOST LIKELY allow for an increase in the number of moles born with a better sense of smell?
A.
More rainfall makes the soil harder for digging so the moles need to have a better sense of smell to locate the worms.
B.
Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of smell to locate the worms.
C.
More rainfall makes the soil easier for digging so the moles need to have a better sense of smell to locate the worms.
D.
Less rainfall causes the worms to burrow further underground so the moles need to have a better sense of smell to locate the worms.
Answer:
I think the answer is D
Explanation:
Because if there is less rainfall that will make it harder for the moles to look for the worms and to sense the worms so they will have to have sense harder or dig harder to get the worms. hope this helps!
Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of smell to locate the worms.
What are adaptations of moles?Moles are adapted to use their sense of smell to locate their food, which is mainly worms. In dry conditions, worms tend to come closer to the surface in search of moisture and as a result, moles would need to have a better sense of smell to locate the worms.
In this scenario, the moles with better sense of smell would be more successful in finding food and would be more likely to survive and reproduce, passing on their advantageous traits to the next generation. This would lead to an increase in the number of moles born with a better sense of smell.

What are the products when a DNA molecule replicates?
A two molecules of DNA each made of a paired sequence of bases
B two molecules of DNA each made of a paired sequence of nucleotides
C two strands of DNA each made of a paired sequence of bases
D two strands of DNA each made of a paired sequence of nucleotides
(Its NOT c.)
The products when a DNA molecule replicates are two molecules of DNA each made of a paired sequence of nucleotides. The correct option is B.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The fundamental mechanism of DNA replication is similar across all organisms, making it a crucial operation.
Two DNA molecules, each consisting of a paired sequence of nucleotides, are produced when a DNA molecule duplicates.
Thus, the correct option is B.
