Its B. They use a universal system of units.
In pigeons, the allele B produces blue feathers. The allele W produces white feathers. The B and W alleles are codominant. A blue and white pigeon BW is crossed with a solid white pigeon WW. What percent of the offspring are expected to be blue and white?
Answer:
The correct answer is - 50%.
Explanation:
Codominance is a type of inheritance that takes place when the genotype of an individual organism in heterozygous condition express traits of both alleles.
Cross between blue and white pigeon and pure white:
BW × WW and gametes will be B and W and W and W
B W
W BW WW
W BW WW
There are 50% of BW that is blue and white pigeons
Which of the following explains why antibiotics will not work against a viral infection?
a
Viruses replicate at such an accelerated rate that antibiotics are unable to control colonization and growth.
b
Viruses create highly resistant endospores that preserve their genetic material against antibiotics.
c
Viruses are not cellular and do not contain the lipid and protein markers targeted by antibiotics.
d
Viruses exchange genetic material with nearby bacteria that have become resistant to antibiotics.
Answer:
C.
Explanation:
Viruses don't have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat.
Why is there limited vegetation in the tundra?
Answer:
Frigid temperatures, etc.
Explanation
The tundra has very low temperatures and a layer of permafrost over the soil. It has characteristics similar to the desert and it also has a short summer and a long, freezing winter. Therefore, there are not many flora variations that can thrive in that biome.
Answer:
The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.

Why does evolutionary theory absolutely require the earth to be very
old?
Answer:
Mainly because Evolution takes millions and millions of years to happen.
Explanation:
Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.
What do you mean by evolution ?Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.
Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.
Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.
Therefore, the Earth needs to be very old for evolutionary theory to be true.

After a forest fire what would be the first change in a forest?
Pioneer species are established
A climax community is established
Wind carries seeds to the area and plants grow from these seeds
New soil forms from rock
c because
The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.
Answer:
Pioneer species are established
Explanation:
A forest fire would represent the process of secondary succession.
In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.
This rich soil allows for pioneer species to grow in the forest.
which product does the Krebs cycle require from the electron transport chain
ATP
CoA
NAD
NADH
pyruvate
NAD +molecule
Explanation:
Krebs cycle and electron transport chain are important steps in cellular respiration.
In the Krebs cycle, there is a need of NAD+ molecule which is then in Krebs cycle reduced to form a NADH2 molecule.
NADH2 is also an energy currency. It , giving electron in electron transport chain and return to Krebs cycle as NAD+.
Now in the Krebs cycle, it is ready to take electrons again.

What is the relationship between population number and carrying capacity in a stable population
Answer:
As a population grows in an area, a population may experience the effects of increased densities. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).

A cotransporter is something that moves two substances across a membrane, one passively and the other actively. The Na+/ K+ ATPase transports sodium and potassium ions across the plasma membrane against their concentration gradients. This pump is not considered a cotransporter because
Answer:
both ions are transported actively
Explanation:
If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.
A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter

Answer: The Sun
3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?
Answer:
Find the explanation below.
Explanation:
When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.
Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.
Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.
Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.
Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
A. If seed shape did not have a clearly recessive form.
