blood enters on the left side of the heart through the_____ and enters the left atrium. Then passes through the_____ to enter the left ventricle 
Blood enters on the left side of the heart through the pulmonary veins and enters the left atrium. Then passes to the mitral(bicuspid valve) to enter the left ventricle.
Blood is a fluid component of the circulatory system that is very vital for transporting oxygen and nutrients in the body system. It comprises cells suspended in plasma.
The correct answers for the blanks are:
Blank 1: Pulmonary veinsBlank 2: Bicuspid valveThe blanks can be explained as:

Cell organelles have different functions that help maintain homeostasis within the
cell. The processes of photosynthesis and cellular respiration depend on these
organelles working properly. Identify the letter of the organelle whose function is to
store water and dissolved salts?
The function of the vacuole is to maintain the turgid pressure that is to maintain the cell turgidity. It stores water along with the dissolved salts in it. The answer is option B.
What are the other parts that are present in the structure of vacuole ?There are various enzymes that are present in the vacuoles and it is just like the pool of the plant cell which stores the various enzymes along with the water molecules and the dissolved salts.
With its roles that perform or help in the plant cell function that are the central vacuole which stores salts, minerals as well as nutrients, along with proteins and pigments that helps in the plant growth and plays important structural kind of role for plant. The organelle that is the central vacuole of plant cells that helps it to just maintain the volume along with the structure.
Vacuoles store the materials like water along with salts and proteins as well as the carbohydrates. Most of the plant cells that are having a single or the large central vacuole. The function of them is that they just store the salts with the sugars with few type of proteins and even the plant colors. They are even working as the storage bags for cell.

Which ingredients are needed to transform NADP+ to NADPH?
an electron and two hydrogen ions
two electrons and two hydrogen ions
two electrons and a hydrogen ion
an electron and a hydrogen ion
Answer: Two electrons and a hydrogen ion
Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
The ingredients needed to transform NADP+ to NADPH are an electron and a hydrogen ion.
Nicotinamide adenine dinucleotide phosphate ion (NADP+) is an energy carrying ion which transfers high energy electrons from chlorophyll to other molecules during photosynthesis.
Photosynthesis is defined as the process by which green plants are able to manufacture their own food.
In the light stage of photosynthesis, the electron and hydrogen atom released during photolysis of water is picked up by the energy carrying ion NADP+.
This is then converted to NADPH, that is Nicotinamide Adenine Dinucleotide Phosphate Hydrogen.

Strawberry cells are octoploid (each cell contains eight copies of chromosomes) whereas banana cells are triploid (each cell contains three copies of chromosomes). Which do you predict will yield a greater quantity of DNA—5 g of strawberry tissue or 5 g of banana tissue? Explain your reasoning.
Answer:
5 g of strawberry tissue
Explanation:
One would expect 5 g of strawberry tissue to yield a greater quantity of DNA because the cells of strawberry have 8 sets of each of the chromosomes in their genomes when compared to the cells of banana with just 3 sets of each of the chromosomes in their genomes. The more the ploidy level of a cell, the more the number of sets of each of the chromosome set and the more the amount of DNA in the cell.

c. biotic factor.
d. indirect observation.
Answer:
b. a limiting factor
An early winter frost that stops a tomato garden's growth is an example of a limiting factor, hence option B is correct.
What is the limiting factor?Anything that limits the size of a population and slows or prevents its growth is referred to as a limiting factor.
Biologic factors including food, mates, and competition with other species for resources are some examples of limiting constraints.
the element that restricts the rate of reaction in any physiological process with lots of variables. the environmental component that has the greatest influence on population size restrictions. Many deer populations are constrained by a shortage of winter forage.
Therefore, winter frost that stops a tomato garden's growth is an example of a limiting factor, hence option B is correct.
