Which of the following best describes how does latitude affect biomes?
Latitudes affect how much rainfall a biome will receive.
Lower latitude biomes will always have high temperature.
Higher latitudes produce warm biomes.
Higher latitudes receive less sunlight producing cold biomes.
Answer:
Higher latitudes receive less sunlight producing cold biomes.
Explanation:
Regions with similar climates and plant types are called biomes.
Terrestrial regions may be classified as desert biomes, rainforest biomes, grassland biomes, temperature deciduous forest biomes, tundra biomes, northern coniferous forest biomes, savanna biomes, and mediterranean biomes.
Because these biomes are mostly defined in terms of dominant vegetation or plant species, they are determined by rainfall and temperature. In general, higher latitude biomes are further away from the equator, less sunlight and heat- this results in drier climates with less rainfall and lower, cooler, temperatures.

A small percentage of the body’s iron supply circulates freely in the blood, bound to a protein called transferrin. Transferrin binds to specific proteins on the surfaces of a cell's plasma membrane. The cell then ingests the transferrin by forming a pit, which becomes a vesicle. Which of the following BEST describes how transferrin is transported across the plasma membrane? A. exocytosis B. pinocytosis C. phagocytosis D. receptor-mediated endocytosis
Answer:
What best describes how transferrin is transported through the erythrocyte plasma membrane is receptor-mediated endocytosis.
Explanation:
The incorporation of transferrin across the erythrocyte membrane depends on a transferrin receptor expressed on the surface of the membrane. The specific receptor recognizes the presence of iron-charged transferrin, transferin diferrica, incorporating it into the cell by endocytosis. Once in the cytoplasm, the iron is dissociated from the transferrin.
Free transferrin is called apotransferrin. The transferrin receptor has a high affinity for transferrin di-ferrica, which facilitates its incorporation by endocytosis, and the release of apotransferrin into the extracellular space.
The other options are not correct because:
A. Exocytosis implies the exit of substances from the cell.
B. Pinocytosis involves the invagination of the membrane to incorporate soluble substances into the cell.
C. Phagocytosis is the incorporation of solid substances by invagination of the membrane.

In general, the land changes temperature much more rapidly than the
ocean. How does this fact explain the existence of land breezes and sea breezes?
Answer:
Answer
Explanation:
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean.

A granite contains zircon crystals with 275 billion 235U atoms and 1925 billion 207Pb atoms. The half-life for 235U-to-207Pb decay is 704 million years. How old is the granite?
Answer:
The correct answer would be = t = 2.112 billion years
Explanation:
Given:
The number of crystal of uranium = 275 billion
The number of crystal of lead = 1925 billion
The half-life for 235U = 704 million years
Formula using :
N = N0e−λt
where,
no. of daughter atoms = N
at time t= 0, No. of parent atoms = N0.
Time = T
Half life = 0.693/λ
Decay constant = λ
Solution:
by putting value in the formula of the half-life
λ = 0.693/0.704
λ = 0.9844
Now, putting value in the formula for the age of granite.
275 = (275+1925)e^-0.9844 t
1/8= e^-0.9844 t
e^0.9844 t = 8
taking log
0.9844t = 2.07944
t = 2.112 billion years
The granite that contains zircon crystals with 275 billion 235U atoms and 1925 billion 207Pb atoms is 2112 million years old.
From the given information:
the total number of parent atoms is equal to the total number of ²³⁵U atoms
= 275 billion + 1925 billion= 2200 billionNow, from these 2200 billion atoms, 1925 billion of ²³⁵U atoms has changed to Pb²⁰⁷ atoms.
So when the number of half-life is: the parent atom is:
0 2200 billion
1 1100 billion
2 550 billion
3 275 billion
It implies that the parent atoms have passed through three half-life;
Thus, the age of the granite(parent atom) is calculated as:
age of granite = n × [tex]\mathbf{T_{1/2}}[/tex]
age of granite = 3 × 704 million years
age of granite = 2112 million years
Therefore, the age of granite is 2112 million years.

What geologic forces drive tectonic movements?
Group of answer choices
seismic movement, volcanic activity, plate tension
Earth's rotation, geothermal activity, gravitational forces
plate subduction, convergence and divergence
Earth's orbit, solar winds, electromagnetic waves
Answer:
Earth's rotation, geothermal activity, gravitational forces
Explanation:
Tectonic movements refers to movement occurring within the earth's crust.
The rotation of the earth on it's axis releases significant amounts of gravitational energy that results in deformation and movement of the earth's crust and mass redistribution of the tectonic plates.
Some of the main forces by which earth's rotation affects tectonic movements are:
Tidal friction due to the gravitational force of the Moon as well the Sun on the earth's crust; and change of the shape of the earth due to small displacements of the rotational pole with respect to the earth's crust.
Geothermal activity is caused by the transfer of heat from depth to the earth's surface. Convection currents in the mantle drive tectonic movements. Within the mantle of the earth, molten magma rises to the top while hot cold solid rock sinks to the bottom setting up a flow known as mantle convection. The rising and sinking motions of materials deform the outer surface of the earth producing earthquakes, mountain ranges, and volcanos on earth.
Two gravitational forces- slab pull and ridge push- cause tectonic movements. Slab pull occurs where gravity pulls
the edge of a cold, dense plate into the asthenosphere due to its weight dragging the entire rigid plate along.
Ridge push occurs when material from a mid-ocean ridge when cooled and thus becoming denser, slides down a raised but weaker asthenosphere due to gravity and push outwards on the lithosphere farther away from the ridges, allowing hot magma from the mantle to flow upwards again.
Answer:
Earth's rotation, geothermal activity, gravitational forces

what is the type and morphology of Escherichia coli
Answer:
E. coli is a Gram-negative, facultative anaerobe (that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent) and nonsporulating bacterium. Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm3.
E.coli colonies on agar.
E. coli on sheep blood agar.
E. coli colonies
E. coli growing on basic cultivation media.
E. coli stains Gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane. During the staining process, E. coli picks up the color of the counterstain safranin and stains pink. The outer membrane surrounding the cell wall provides a barrier to certain antibiotics such that E. coli is not damaged by penicillin.Strains that possess flagella are motile. The flagella have a peritrichous arrangement.It also attaches and effaces to the microvilli of the intestines via an adhesion molecule known as intimin.
Explanation:
Suppose that Rosie and Ross are both carriers for PKU (a rare autosomal recessive disease.) If they have eight children, what is the probability that all of eight children will have the same phenotype?
Answer:
1/65,536 = 0.001523 %
Explanation:
A: normal allele
a: recessive allele causing PKU
The probability that Rosie and Ross have one child with PKU will be >>
Aa x Aa = 1/4 AA; 1/2 Aa; 1/4 aa
In consequence, the probability that Rosie and Ross have eight children with PKU will be >>
(1/4)⁸ = 1/65,536 = 0.001523 %
If Rosie and Ross are carriers of PKU, if they intend having 8 children, the probability that they will all have the same phenotype is: [tex]\mathbf{\frac{1}{65,536}; 0.001523 \%}[/tex]
Given that Rosie and Ross are both carriers of the recessive disease, it means that for the disease to manifest itself, two recessive alleles must be present in an allelic pair.
Using P and p to denote the dominant and recessive alleles respectively, we have the following gene of both parents:
Rosie - PpRoss - PpThe cross between both parents has been provided using a Punnett square as shown in the attachment.
The cross shows that, for any cross between both parents, there is [tex]\frac{1}{4}[/tex] probability that the child would have the phenotype, pp, which means the child would have the are autosomal recessive disease.
Therefore, the probability for for 8 children having the same phenotype will be:
[tex]\frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{65,536}[/tex]
This is also approximately: [tex]\frac{1}{65,536} \times 100 = 0.001523 \%[/tex]
Therefore, if Rosie and Ross are carriers of PKU, if they intend having 8 children, the probability that they will all have the same phenotype is: [tex]\mathbf{\frac{1}{65,536}; 0.001523 \%}[/tex]
