The Cell TheoryThe smallest living things are one-celled or ____+_______________Large organisms contain millions of cells. They are many-celled or _________________ ____________________________.All of the organism's life functions are carried out by cells or parts of cells.Cells develop from other living cells – not from nonliving matter.
Answer:
unicellular; multicellular
Explanation:
The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be unicellular while those that are made up of multiple cells are said to be multicellular. Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?
The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.
What is nucleus?The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.
DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.
The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.
The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.
Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.
Thus, nucleus is only present is eukaryotic cells.

One of the differences between embryonic stem cells and adult stem cells is ?
Answer:
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cells can become all cell types of the body because they are pluripotent.
Which statement best describes how homologous chromosomes are
separated during meiosis I?
A. The sister chromatids of each chromosome separate into different daughter
cells.
B. The two homologous chromosomes are not separated during meiosis I.
C. The two homologous chromosomes travel together into one new daughter cell.
D. The nonsister chromatids of each homologous pairs separate into different
daughter cells.
The two homologous chromosomes separate into two different daughter cells.
Answer:
two homologous chromosomes travel together into one new daughter cell.
Explanation:
in metaphase I the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. in anaphase I centromeres break down and homologous chromosomes separate. in telophase I chromosomes move to opposite pols; during cytokinesis the cell separates into haploid cells.

can someone pls help me with this
Answer:
t= log2(2048)
The logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In this case:
[tex] {t}^{2} = 2048[/tex]
[tex]t = \sqrt{2048} = 45.3h[/tex]

25% red, 50% pink, and 25% white
Explanation:
construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.
RR is red and occurs once so that is a 25% chance (1/4)
RW is pink and it occurs twice so that is 50% (2/4)
WW is white which occurs once and it is another 25% (1/4)

Explanation:
if wrong then sry
Answer:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process huge amount of energy is created.
A space used in industry or research settings that has a controlled level of contaminants is called a __________.
Answer:
Clean room.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.
A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.

what is gene flow and how might it impact a wolf population
Answer:
Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.
Explanation:
Gene flow within the population increases the genetic variability in the wolf population variation can be seen.
What is gene flow?Gene migration is another name for gene movement. The movement of genetic material from one group to another is referred to as gene flow.
Through migration, gene flow can occur between two populations of the same species and is mediated via vertical gene transmission from parent to offspring and reproduction.
Any movement of people and the genetic material they carry from one community to another is referred to as gene flow, often known as migration.
Therefore the movement of genetic material from one population to another is known as gene flow.

one of the seed banks has been storing seeds of a rare and endangered plant to keep the seeds fresh.120 of the seeds of this plant were selected to be grown out of this 120 seeds only 90 germinated
what percentage of the seeds was not fertile?show all your working
Answer:
25%
Explanation:
According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.
This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:
30/120 × 100
= 1/4 × 100
= 100/4
= 25% of the selected seeds are infertile.
