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
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

Some tools have various levels of graduations. For example, a ruler may have graduations for both millimeters and centimeters. When measuring the length of an earthworm, which graduations would allow for the most accurate measurement?
millimeters
centimeters
decimeters
meters
Answer: A
Explanation:
I took the test
Millimeters allow for the most accurate measurement.
Is cm extra accurate than mm?
A paper clip may be measured with both units (millimeter or centimeter) but a millimeter is the greater appropriate size to get an accurate measurement.
Why are millimeters more specific?A ruler marked in millimeters is extra unique than a ruler marked best in centimeters, considering a millimeter is a smaller unit than a centimeter.

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.
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).

How does the Gulf Stream affect weather in the United States? A. It brings cooler temperatures from the poles. B. It brings cooler temperatures from the tropics. C. The warm surface currents help create storms and fog. D. The cool surface currents produce cooler weather and fog.
Answer: C. The warm surface currents help create storms and fog.
Explanation:
The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.
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.
Answer:
NAD+

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.

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.
