Answer:
9:3:3:1
Explanation:
This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.
Assuming the colour is White (P) and Black (p) and the
Height is Tall (T) and short (t)
The possible phenotypes will be in the ration
9 - White and Tall
3 - White and short
3 - Black and Tall
1 - Black and short
It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.

chemical composition of the Rough endoplasmic reticulum
Answer:
The rough endoplasmic reticulum consists of two dimensional flattened sacs formed from phospholipids and ribosomes.
Explanation:
Genes within DNA are expressed through transcription and translation of the genetic code.
The rough Er contains important machinery in gene expressions, Ribosomes embedded in a lipid membrane. These are small sub cellular organelles that carry out a specific function of protein manufacturing and modulation. They contain the translocon complex, integral to the translation process
The endoplasmic retuculum consists of folded phospholipid membrane sheets or cisternae- these are mainly two dimentional, and form flat sacs.These provide small specific environments from the cytosol in the cytoplasm- they span the entire cytoplasm.

Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?
Answer:
Explanation:
The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.
How are euglena and kelp alike and different?
Answer:
ALIKE: plant-like protists with chloroplast
DIFFERENT: euglena is a single celled alga and uses flagellum to move from place to place. Kelp is a multicelled alga

What are 2 pieces of evidence that support the Continental Drift Theory? Explain how they support the theory.
Answer:
Explanation: In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
The fit of the continents; the dispersion of ancient fossils, rocks, as well as highlands; and the positions of ancient climatic zones were all evidence for continental drift.
What is Continental Drift Theory?Continental drift was a groundbreaking theory that explained how continents shift position on the Earth's surface.
Alfred Wegener, a geophysicist and meteorologist, proposed the theory in 1912, but it was rejected by mainstream science at the time.
Plate tectonics caused continental drift over millions of years. Plate tectonics also explained how plate movement causes volcanoes and earthquakes, as well as how continent collisions create massive mountain ranges.
Continental drift was demonstrated by the fit of the continents, the dispersion of ancient fossils, rocks, and highlands, and the positions of ancient climatic zones.
Thus, these are the evidences that support the Continental Drift Theory.

Calvin cycle:
In Calvin cycle number of carbon atoms are constant in CO₂ and used to construct three-carbon sugars. This manner is fueled by, and established on, ATP and NADPH from the mild reactions.The Calvin cycle reactions occurs in three main stages: carbon fixation, reduction, and regeneration of the starting molecule.So, in the question it is asked how many G3P would be produced if there are 36 carbon dioxide that enters the Calvin cycle. Thus the answer is 12
In order for one G3P to go out the cycle (and move in the direction of glucose synthesis), 3 CO₂ molecules need to input the cycle, imparting 3 new atoms of constant carbon.

Answer:
The inheritance pattern of these traits will be independent. However, it will depend on the factor that which trait is dominant or recessive. It might also show incomplete dominance.
The different genotypes that organisms of this population might have are aa, ab, ac, bb, bc , cc. If neither of the alleles are completely dominant over the other, then incomplete dominance might exist for such genes.

Babies that hatch out of the egg with eyes wide open, fully feathered, and able to run around and find food in minutes are called
Answer: The question is incomplete and options are not given, here are the options.
A. Atricial
B. Precocial
C. Hyperbole
D. Hyperactive.
The correct option is precocial.
Explanation:
It is precocial because it is the ability of new hatched birds with full feathers and eye open to be able to move around and find food after been hatched from the egg. It is common in birds and it is gotten from Latin word called precoccous. Some newly hatched birds can be able to mobilise around minutes after hatching and search for food while some cannot move around minutes after hatching to search for food, this type of birds are called Altricial.

A
Glucose is transported into the cell by active transport
Subm
B
Nat is transported into the cell by active transport
с
The movement of glucose through the membrane requires ATP hydrolysis
D
Na transport out of the cell requires ATP hydrolysis
Answer:
The correct answer is - D . Na transport out of the cell requires ATP hydrolysis
Explanation:
Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.
Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.
The given diagram represents the transport of sodium out of the cell using active transport. Active transport utilises the energy or ATP released during respiration. The correct answer is that sodium is transported out of the cell requires ATP.
Active transport is defined as the transport in which molecules move from lower to higher concentration, against the concentration gradient. The active transport requires the hydrolysis of energy to move across the cell. The sodium-potassium pump follows the active transport, such that:
The pumping of ions against the concentration gradient requires the addition of energy. The high-energy molecule is used to facilitate the active transport of sodium ions during the sodium-potassium pump.Therefore, the image represents the sodium is transported out of the cell by active transport.
