3.give an example of unicellular organism._____________
4.differentiate a unicellular organism from a multicellular organism._________________
5.can there be tissues,organs and systems without cells? support your answer._____________
Answers
2- No, because some unicellular organisms like bacteria only consist of 1 cell.
3- An example is bacteria, amoeba, etc.
4- Multicellular organism consist of different cells and mostly have different specialized cells. Unicellular organisms carry out their functions like multicellular, but all in 1 cell. They are known to be smaller than multicellular organisms.
5- No, because cells are the building blocks of life and you need cells to form together to form tissues, later into organs and organ systems. Tissues and organs function due to the amount of cells functioning. Tissues and organs are the formation of cells that serve a function to create more complex systems.

Answers
Answer:
Without the tree the cow couldn't live.

The data table shows the percentage of amino acid
similarities found in a protein for several organisms
when compared to the same protein in rabbits.
Based on the data,which organism is most closely related to the rabbit?
a.hamster
b.pig
c.dog
d.cat
Answers
Based on the data, the organism that is most closely related to the rabbit is: b. Pig.
Which organism has the most similarity?According to the diagram, the organism that has the most closely related similarity to the rabbit is the pig. The pig bears 95.4% of amino acid similarity to the Rabbit. This is almost 100 percent similarity, so we can say that this animal bears the most resemblance to a rabbit.
Amino acids are base materials that are necessary for the formation of nucleotides and genetic materials so the similarity goes down to genetics.

Answer:
2-Air masses are colliding with each other.
Explanation:

From the image given below its clear that the warm is rising upwards and as a result of the collision from the cold winds or front from below, hence the development of clouds that make the thunderstorms appear.And a result of this turbulent the rising air is pushed and the warm front cycle takes a turn and will lead to either development of cyclone or rainfall.Describe at least two of the four major systems we looked at in class: Ice, Water, Land, Atmosphere and

Does the sodium-potassium pump move?
Answers
Answer:
The pumping method of sodium-potassium pushes sodium and potassium ions against elevated concentration levels. It transfers two potassium ions into the cell where the levels of potassium are high, and pumps three sodium ions into the extracellular fluid and out of the cell.
Explanation:
ATP's hydrolysis is an active transport mechanism by the passage of sodium and potassium ions across the cell membrane to provide the required energy.
When cells want to store up energy will they add or delete a phosphate group
Answers

Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.
A tall pea plant with red flowers has the genotype TtRr. This plant is crossed with another tall pea plant with white flowers, having the genotype Ttrr. What is the probability of getting dwarf plants with red flowers in the F1 progeny
Answers
Answer:
1/8 or 12.5%
Explanation:
This question involves two genes coding for height and flower color in pea plant. The alleles for tallness (T) and red flowers (R) are dominant over the alleles of short (t) and white flowers (r).
According to this question, a tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr). The following gametes is produced by each parent:
TtRr - TR, Tr, tR and tr
Ttrr - Tr, Tr, tr and TR
Using these gametes in a punnet square (see attached image), the following proportion of F1 offsprings will be produced as follows:
Tall, Red (T_R_) = 6
Tall, white (T_rr) = 6
Dwarf, red (ttR_) = 2
Dwarf, white (ttrr) = 2
The probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.
Answer:
12.5
