which muscle characteristic describes the ability of muscle to respond to a stimulus?
hiya!
"Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched."
Examine the image of the relatedness of vertebrates represented in this phylogenetic tree. Select all the statements
that are supported by this tree.
A)
Gray whales are the common ancestor of the Blue and Humpback whales.
B)
Blue and humpback whales diverged more recently than either did from
the gray whale
The Bryde's whale shares a more recent common ancestor with the Sei
whale than with the Fin whale.
D
The blue and the Bryde's whale have more traits in common with each
other than with any other two species,
E
Southern minke whales and Northern minke whales have more traits in
common with each other than with any other species
By analyzing a phylogenetic tree, we can establish relationships between different taxonomic groups. Nodes, branches, and lineages provide information for these interpretations. The statements are C and E.
--------------------------------------
The phylogenetic tree is composed of,
Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.
⇒ Highly related groups that share a recent common ancestor. This means that they all diverge from the same node.
⇒ Lineages less related to each other are those whose common ancestor is far away in history.
A) Gray whales are the common ancestor of the Blue and Humpback whales. ⇒⇒⇒ NO
B) Blue and humpback whales diverged more recently than either did from
the gray whale ⇒⇒⇒ NO
C) The Bryde's whale shares a more recent common ancestor with the Sei

D) The blue and the Bryde's whale have more traits in common with each

Answer:
Explanation:
One of the most important aspects of bioinformatics is identifying genes within a long DNA sequence. Until the development of bioinformatics, the only way to locate genes along the chromosome was to study their behavior in the organism (in vivo) or isolate the DNA and study it in a test tube (in vitro).

in eukaryotes, one distinct feature of chromosome organization that is different from prokaryotes is __________.
Prokaryotes are creatures made up of cells without cell nuclei or any membrane-enclosed organelles.
What difference in organelle in eukaryotes and prokaryotes?
Eukaryotic cells, which are defined as cells with organelles that are membrane-bound, are the building blocks of both unicellular and multicellular organisms.
Prokaryotic cells, in contrast, are invariably seen in unicellular organisms and lack any membrane-bound organelles.
Eukaryotes are organisms made up of cells that have membrane-bound organelles and a nucleus that houses genetic material.
Therefore, in eukaryotes, one distinct feature of chromosome organization that is different from prokaryotes is nucleus.

consider a stable frog population living at carrying capacity in a pond. an average female produces 6,000 eggs during her lifetime and an average of 300 tadpoles hatch from these eggs. for the population size to remain stable, how many of these tadpoles should, on average, survive to reproduce?
Answer:
Uhmmmm, Since out of 6,000 eggs, 300 would hatch on average. The amount of tadpols to most likely survive would be 10-30. (I think)
The same species in an ecosystem living in a group is called population. The attribute of the population is the sex ratio, population, birth ratio, and death ratio.
The answer is 5% of the tadpole.
The fusion of the male and female gamete is called reproduction which leads to the formation of new offspring which carry the genes to the next generation.
To remain stable in the population is 5% of the tadpole because the tadpole formed survive after the egg is 5% of the total.
Hence, the 50 tadpoles must survive to have a stable population.

⭐Pls help me Fast!⭐
As stated in the preceding statement You will most probably find specialized tissue in bacteria.
The correct option is D.
Definition of a bacteria in simple terms:The simplest single-celled organisms are known as bacteria, and they are invisible to the unaided eye. Various animals, including humans, include a wide variety of microbes both inside and outside. Additionally, bacteria are vital components of the Earth's ecosystems since they are present in food, water, soil, and surfaces.
What distinguishes a bacterium from a bacteria?The word "bacteria," which is plural, is spelled "bacterium." To put it another way, you use the word "bacteria" when there are multiple of them and "bacterium" and there is only one.
Why do bacterial infections occur?When bacteria taken into the body, multiply, and trigger an immune response in the body, a bacterial infection results. Through an opening within your skin, such as a cut or surgical wound, either through your airway, germs can enter your body and cause diseases like bacterial pneumonia.

Answer:
A polygenic trait is controlled by multiple genes and influenced by the environment.
Explanation:
A Polygenetic trait is a group of non-epistatic genes that interact to influence a trait. Essentially, in short terms Polygenetic traits are controlled by multiple genes rather then an individual inherit gene.
Hope I helped,
Brainliest is always appreciated.
Answer:
B: A polygenic trait is controlled by multiple genes and influenced by the environment
Explanation: For anyone who wants/needs an explanation
Polygenic traits basically mean the traits that are a result of multiple intertwined traits like for example skin colour.
When two people mate their traits get intertwined and the resultant trait of the baby is a result of the polygenic traits.
Polygenic traits are controlled by more than one genes. An example of this on humans is height. Not one gene controls the height of a human, many traits contribute to the height of a human.
