Answer:
H.) The offspring will have the correct number of chromosomes when the sperm and egg are joined
Explanation:
This is because the sperm has 23 number of chromosomes and the egg has 23 number of chromosomes as well. When they fuse, they from 46 chromosomes.
Answer:
I think it is H.
before the egg and sperm join they have half of the chromosomes each when they join the chromosomes add up to the right amount which is 46

Is sand called sand because its in between the sea and the land?
I'm asking the questions that need to be asked people! :'D
No, not at all. ... The English word 'sand' comes from Old Dutch/proto-German 'zand', which has nothing to do with either sea OR land, but referred originally to unstable ground, as near rivers.
I hate the English language sometimes, like: "waterfall". But anyways, I hope this helps ^^
Hmmm... I've never thought of that before... nice catch lol

why is it important to have maps of the ocean floor, such as those gathered with SeaBeam technology
Since oceans cover 71% of the Earth’s surface, understanding what the seafloor looks like, and where different processes, such as ocean currents are active, is hugely important. Mapping the seafloor helps to work out things like where different types of fish live, where resources may be, such as rare metals and fossil fuels, and whether there is a risk of underwater landslides happening that might cause a tsunami. Mapping the seafloor is very challenging, because some cannot use the same techniques that some would use on land. To map the deep ocean, there's a tool used called a multibeam echo-sounder, which is attached to a ship or a submarine vessel.

Not a long life story but a simple two reasons.
Answer:
1-Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli.
2-They also don't reproduce independently but must replicate by invading living cells.

Veronica wrote Charles Darwin’s main points on the board, but she made a mistake in one point.
1. Since more offspring are produced than an environment can support, organisms within a population must compete for resources to survive.
2. Due to variations within the population, some competitors will be better equipped for survival than others.
3. The best-equipped organisms will survive and will produce well-equipped offspring.
4. Variations that help with survival will be passed on to future generations and will rapidly change the whole population.
Which point is flawed as written above?
point 1
point 2
point 3
point 4
Answer: the answer is 4. Variations that help with survival will be passed on to future generations and will rapidly change the whole population.

Each trait of a plant is determined by
one gene
one dominant gene
a pair of genes
an allele
Answer: an allele .
Explanation:
!!PLEASE HELP RN!! what are 3 similarities that dominant and recessive alleles have?
Answer:
When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.
Explanation:
Answer:
we've found a lot of dominant alleles to be gain of function, whereas recessive alleles tend to be loss of function.

taj incorrectly states that autographs are also known as consumers that need to feed on other organisms, including plants and animals, to gain energy. which of the following best describes consumers that feed on other organisms such as plants and animals for energy?
A. carnivores
B. trophic levels
C. heterotrophs
D. herbivores
Herbivores best describes consumers that feed on other organisms such as plants and animals for energy.
What do you mean by herbivores?A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.
Many herbivores have large, dull, flat teeth. These teeth are excellent for chewing and breaking down tough plant material. Carnivores have sharp, narrow teeth that are better for biting and tearing flesh. However, some herbivores also have strong, sharp teeth.
Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses.

Fossil remains of Glossopteris (an extinct plant with large leaves) have been discovered in India and Australia. When they were living, all the Glossopteris were located together on land, but now the Glossopteris fossils are separated by an ocean. What could explain how these fossils got so far apart?
Answer:
Due to splitting of lands.
Explanation:
These Glossopteris fossils got so far apart from each other because of the splitting of super continent about 175 million years ago. Before 175 million years, India and Australia are attached to each other and these Glossopteris plants are present on these lands but with the passage of time, the lands of India and Australia split and go far away from each other so due to splitting of lands, these fossils got so far apart from each other.
if a sample known to be about 11,460 years old and has 400 carbon 14 Adams how many atoms are in the sample when organisms just died
Answer:
There are 1600 atoms when organism just died.
Explanation:
The statement is incorrect. The correct statement is:
If a sample known to be about 11,460 years old and has 400 carbon 14 atoms. How many atoms are in the sample when organisms just died?
The amount of atoms associated with radioactive isotopes decreases exponentially in time by means of the following formula:
[tex]n(t) = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial amount of atoms.
[tex]n(t)[/tex] - Current amount of atoms.
[tex]t[/tex] - Time, measured in years.
[tex]\tau[/tex] - Time constant, measured in years.
In addition, the time constant can be calculated in terms of the half-life of the radioactive isotope ([tex]t_{1/2}[/tex]), measured in years:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
If we know that [tex]t_{1/2} = 5,730\,yr[/tex], [tex]t = 11,460\,yr[/tex] and [tex]n(11,460\,yr) = 400[/tex], then the initial amount of atoms is:
[tex]n_{o} = \frac{n(t)}{e^{-\frac{t}{\tau} }}[/tex]
[tex]\tau = \frac{5,730\,yr}{\ln 2}[/tex]
[tex]\tau \approx 8,266.643\,yr[/tex]
[tex]n_{o} = \frac{400}{e^{-\frac{11,460\,yr}{8,266.643\,yr} }}[/tex]
[tex]n_{o} \approx 1600[/tex]
There are 1600 atoms when organism just died.

what is the problem with organizing organisms taxonomically purely based on their physical traits
Answer:
See the answer below
Explanation:
The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.
Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.
Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.

the ages of 9 and 19?
A. It triples in size, from 3 to 9 individuals.
B. It grows steadily.
C. It remains the same size.
D. It drops from 9 to 3 individuals
Answer:
D is the correct answer
Explanation:
It drops from 9 to 3 individuals to the female population between the ages of 9 and 19.
What is population?A population is made up of every organism of a specific species that resides in a specific location. Demography is the statistical study of populations and how they evolve through time.
Population size, or the total number of people, and population density, or the number of people per unit of space or volume, are two crucial indicators of a population. Ecologists use quadrats and the mark-recapture technique to evaluate the size and density of populations.
A population of organisms may be dispersed randomly, uniformly, or clumped. When a population is described as uniform, it is evenly spaced, random indicates uneven spacing, and clumped, it is dispersed in groups.
Therefore, It drops from 9 to 3 individuals to the female population between the ages of 9 and 19.
