What is original cell theory?All living things are made up of one or more cells, which is one of the three principles of the cell theory. The fundamental unit of structure and organization in organisms is the cell.
While doing studies on tissues in the late 1830s, zoologist Theodor Schwann and botanist Matthias Schleiden proposed the united cell theory.
The unified cell theory states that each living thing is composed of one or even more cells, every cell is the basis of life, and new cells can be created from existing cells.
Therefore, cell produce through the spontaneous generation.

Using evidence from the video, describe three characteristics of life that Archaea bacteria have.
A image of Archaea micro organism within the video confirmed that the body is made of a unmarried cellular, and has a described boundary. Scientists also realize that it reproduces by transmitting its genetic facts because there's proof of Archaea genes in our DNA nowadays.
The three traits of lifestyles that Archaea micro organism have are:not unusual characteristics of Archae bacteria known to this point are: (1) the presence of a feature of tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan mobile partitions, in most instances, in preference to a huge protein-wealthy coat; (three) the formation of ether-related lipids formed through phytanyl chains.
what's the difference among micro organism and archaea micro organism?Like micro organism, archaea have no inner membrane however both have cellular partitions and use flagella for swimming. Archaea differs from the reality that their cell wall does not include peptidoglycan and that the cell membrane makes use of ether-linked lipids rather than an ester connected to lipids in micro organism.

Drag each label to the correct location. Identify the cell organelles found only in plant cells and those found in both animal and plant cells. nucleus cell wall chloroplast Golgi apparatus cell membrane ribosome
Answer:
Plant cell: chloroplast, cell wall
animal and plant cells: nucleus, cell membrane, ribosome, golgi apparatus
Explanation:
The organelles that are specific to the plant cell only among the listed organelles include chloroplast and cell wall, while those found in both animal and plant cells include the nucleus, cell membrane, ribosome, and golgi apparatus.
The chloroplast contains the green pigment (the chlorophyll) that is present in all green plants. It is the organelle that confers greenness to plants and is therefore absent in animal cells. The rigid cell wall is only found in plant cells and this confers a kind of hexagonal shape to the cell, unlike the animal cell that lacks a rigid cell wall and therefore, shapeless.
All eukaryotic cells, including plant and animal cells, posses nucleus. It is an organelle that houses the genetic materials of the cell and acts as the control center of the cell. The cell membrane is also common to both cell and acts as a selectively permeable membrane to the cells. The ribosome is the organelle responsible for protein synthesis in both plant and animal cells while the golgi apparatus plays an important role in secretory pathway in both cells.

A. Short range message molecules
B. Direct contact
C. Hormones
D. Enzymes
Answer:
C: Hormones
Explanation:
hormones do not "signal" other cells. I hope this helps :)
The correct answer is option C. Hormones.
What is the simple definition of hormones?Hormones are chemicals that act like messenger substances in the body. After being made in one part of the body, they move to other parts of the body, where they help control how cells and organs work. For example, insulin is a hormone made by the beta cells of the pancreas.
In endocrine signaling, signaling molecules (hormones) are secreted by specialized endocrine cells and transported through the circulatory system to affect target cells in remote parts of the body.
Hormones are so many essential parts of your body's system that they regulate much of what your body does. Hormones regulate growth, libido, sexual development, reproduction, sexual function, metabolism, and thirst, among other things. They simply tell the body what to do to keep it running smoothly.

A sexually reproducing animal has two unlinked genes (on separate chromosomes), one for head shape (H) and one for tail length (T). Its genotype is HhTt. Which of the following genotypes is possible in a gamete from this organism assuming no errors in meiosis?
a) HT
b) Hh
c) HhTt
d) T
e) tt
Answer:
a) HT
Explanation:
This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.
Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.
Therefore, HT is the genotype possible in a gamete of parent: HhTt.
Place cells, which are located in the hippocampus, become active in birds when searching for previously-hidden food. Helping them remember where things are, these cells help animals create a:____________
Answer:
Spatial memory
Explanation:
When the need arise to plan and manoeuvre ones way out of a familiar location,or to recollect where particular object is located or an incident happened, the type of memory stored and retrieved from the brain is called Spatial memory.
Generally,animals store information about their environments during their itineraries at different locations,as spatial representation memories of the environments.These are stored in their hippocampus. These are retrieved each time they need to navigate in the environment.
Generally the hippocampus located in the temporal lobes,and medial temporal lobes are the sites where the spatial memory of the environment is stored,and retrieved by the animals(birds)
Generally the hippocampus is the region of the brain which helps to produce ,consolidates,and recollects memories of a specific events in all animals.
