Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.

Which of the following is a disadvantage to using chlorine for disinfection of water?
Answer:
Damage our health.
Explanation:
The levels of chlorine used for disinfection of drinking water causes long-term health effects because chlorine is toxic substance that greatly damaged cells and tissues of our body. Chlorine has low protection against protozoa due to its ineffectiveness on the protozoans organisms. These protozoa also adversely affected our health so we can say that chlorine has to be used in a limit which does not harm our body.
Answer:
Chlorine reacts with organic compounds.
Explanation:
Chlorine reacts with organic matter to create chlorination byproducts which often change the overall chemical properties of water.
Cross two pink snapdragons. What is the genotypic and phenotypic probability of such a cross?
Answer:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
Explanation:
This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.
According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white

Please help Why must animals eat food but plants do not eat food?(1 point) Plants do not appear to eat, but they do actually eat nutrients in the soil. Animals must eat to obtain food that they can't get from the soil. Plants make their own food through photosynthesis, so they do not eat. Animals eat because the energy they make themselves is enough to live but not grow. By eating, they can grow big and strong. Plants use photosynthesis to make their own food instead of eating. Animals eat plants because they like the taste of certain fruits. Plants make their own food through photosynthesis. Animals must eat because they cannot make their own food.
Answer:
Because they will die if they don't eat food, they need the protein to keep them moving and there muscles strong. Some animals get food off of other animals.
Explanation:
Answer:
Explanation:
Well there is animals who only Eat plants and not other animals

Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures
Answer:
B and D
Explanation:
Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.
The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.
So, option B and D are correct one.
Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct

Choking on food is most likely caused by an interference with the proper functioning of the...
Answer:
esophagus
Explanation:
the esophagus is the pipe/muscle that leads to your stomach
Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.
What is oesophagus?
The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.
The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.
The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.
Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

Answer:
C. P -› F1 -› F2
Explanation:
In genetics and breeding, the following symbols represents the following:
P => parental
F1 => First filial generation
F2 => Second Filial generation
The crossing of two parent plants (P) produces offspring that is tagged the first filial generation (F1). The next cross involving the F1 offspring produced second filial generation (F2).
Therefore, the correct sequence is:
P -› F1 -› F2

30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample 30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample
Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

After mitosis and cell division are over how are the two new cells similar to the original cell in interphase??
Answer:
Explanation:
In s phase, the dna replication take place in interphase, The dna in the nucleus replicates so that each chromosome consists of two identical chromatids, then in mitosis they are pulled apart in anaphase in which both cells have half of the chromosomes, in Telophase each chromatid contains one dna molecule, which will replicate itself during interphase before the next division.
The new cells are similar from the original ones in interphase as these will have same amount of DNAs.
What is interphase?The interphase phase of the cell cycle is where the majority of the life of a typical cell occurs.
Interphase is the cell's "daily living" or metabolic phase, during which it obtains and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.
The cell cycle's longest phase is interphase. This is the stage at which the cell grows and copies its DNA before entering mitosis.
Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.
In interphase, the new cells are similar to the original ones because they have the same number of DNAs.
Thus, this can be the similarity between these two.
