Explain the three principles of the cell theory
Answer:
The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Explanation:
Can I have brainliest?
Answer:
Answer: 1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.
Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

IM GIVING 40 POINTS !! DONT SKIP :((.
Answer:
You answer is B
Explanation:
This is the only possible answer because when animals die they might get trapped under layers of bone conserving the bone, and B is the answer because if bones are conserved in the sediment Scientists may be able to recognize certain animals for example, 1000 years ago a cow dies and is buried by sediment, the skeleton remains allowing scientists in the present year to analyze it, they might notice slight changes in things like the bones, or the teeth, etcetera, thus this is how Scientists found proof of evolution.

balance the equation: KrF2+H2O -> Kr + O2 + Hf (the numbers are actually subscripts i just cant make them tiny on my keyboard
Answer:
KrF2 + H2O -> Kr + O2 +2HF
Explanation:
You would just need to add a 2 on the HF, because on both sides it can balance with 2F's and 2 H's

Describe the organization of a synovial joint.
Answer:
The bones of a synovial joint are surrounded by a synovial capsule, which secretes synovial fluid to lubricate and nourish the joint while acting as a shock absorber. The ends of the joint bones are covered with smooth, glass-like hyaline cartilage which reduces friction during movement.

When DNA replication occurs before meiosis, the original DNA strand
GTC ACA GGC ATC is copied into complementary strand CAG CCG TAG.
What type of mutation has occurred?
A) deletion
B) insertion
o
inversion
D) translocation
In this particular insertion there is an insert of three bases. Complementary strands in DNA are the opposite strand, so Adenine is coupled to Thymine and Guanine is coupled to Cytosine.
#BrainlyIsFunwhat is hormone injection and subcutaneous implants??
Explanation:
The contraceptive injection is a shot that contains hormones, either a progestin alone, or a progestin and an estrogen together, that stop your body from releasing eggs and thickens the mucus at the cervix. You need one shot either once every month or once every three months from a healthcare provider. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped. The way it works is similar to the pill, or the ring, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.
Algal bloom is caused what 2 factors in the dead zone?
0 points
A) Fertilizer
B) Nitrogen
C) Nutrient
D) Rapid growth
E) Phosphorus
F) Animal waste
pls help i need this because of a quiz
tbm queria saber essa pergunta!!
Answer:
Dead zones are generally caused by significant nutrient pollution, and are primarily a problem for bays, lakes and coastal waters since they receive excess nutrients from upstream sources. Excess nitrogen and phosphorus cause an overgrowth of algae in a short period of time, also called algae blooms.

Which of the following is not a function of tRNA
Answer:
connecting amino acid together to form proteins
hope it will help
Option D is correct. "connecting amino acid together to form a protein" is not a function of tRNA
Unlike DNA, there are three types of RNA that are involved in protein synthesis, messenger RNA, ribosomal RNA, and transfer RNA.
Ribosomal RNA (rRNA) and transfer RNA (tRNA) are not copies of the info in DNA, instead, their codes are created while in the DNA and then cut into smaller coded fragments.
Transfer RNA (tRNA) is found in cells' cytoplasm and ensures the correct amino acids are carried to mRNA codons to form polypeptide chains during protein synthesis. tRNA takes the amino acid to the correct location for protein synthesis in the ribosome.
Some of the functions of tRNA include:
Picking up amino acid specified by the codonTranscribing nitrogen bases into mRNA in the nucleus Recognizing appropriate codon in the mRNAAccording to the explanation above, we can see that "connecting amino acids together to form a protein" is not a function of tRNA

How are tropical rain forests and temperate forests different?
A. Temperate forests have more biodiversity.
B. Temperate forests are more productive.
C. Temperate forests are closer to the equator.
D. Temperate forests have more seasonal changes.
Answer:
d
Explanation:
Tropical rainforests are found closer to the equator where it is warm. Temperate rainforests are found near the cooler coastal areas further north or south of the equator. The tropical rainforest is a hot, moist biome where it rains all year long.
Tropical rain forests and temperate forests are different because temperate forests have more seasonal changes.
How are tropical rain forests different from temperate forests?Tropical rainforests are found closer to the equator having less seasonal changes while on the other hand, temperate rainforests are found near the cooler regions having more seasonal changes.
So we can conclude that tropical rain forests and temperate forests are differen because temperate forests have more seasonal changes.

According to the chart below, which planet contains the most hydrogen gas?
Saturn
Jupiter
Venus
Earth
Answer:
Saturn
Explanation:
As you can see from the chart, the hydrogen gas is labeled by the turqoise part of the bar chart. To find which one has the most hydrogen gas, select the planet where the bar with hydrogen gas is the highest. If you compare, you will notice that neptune and jupiter have the least because the hydrogen gas is lowest on the bar chart, Saturn and uranus have a higher concentration of this gas but saturn has more than uranus respectively.

Nerve cells do not replicate their DNA after reaching maturity. A cell biologist observed that there was x amount of DNA in a human nerve cell. In four other types of human cells, labeled A-D, she measured the following amounts of DNA:
cell A, 2x; cell B, 1.6x; cell C, 0.5x; cell D, x
Match the four cell types with the following choices: (1) sperm cell; (2) bone cell just beginning interphase; (3) skin cell in the S phase; (4) intestinal cell beginning mitosis. (Hint: review the phases of the cell cycle and mitosis in chapter 12 if needed!).
Cell Types, Amount of DNA - Specific Cell
cell A, 2x:
cell B, 1.5x:
cell C, 0.5x:
cell D, x:
Answer:
Cell A= Intestinal cell begining mitosis
Cell B= Skin cell in S phases
Cell C= sperm cell
Cell D= bone cell just beginning interphase
