Vestigial structuresserve little or no present purpose for an organism. The human tail, which is reduced to the tailbone during development, is one example.
Mitochondria are cell structures that contain a small quantity of DNA.
Scientists are sequencing the DNA of one particular gene in mitochondria to
help identify different species of many animals including myriapods. The
sequences that they find are called ‘barcodes’.

Alice and her friends looked at a bunch of ladybugs. They noticed the ladybugs had different numbers of spots. They each had different ideas about why the numbers of spots were different.
This is what they said: Which person do you agree with the most?
A) Karen: I think they must all be different species of ladybugs.
B)Troy: I think each ladybug has the same number of spots as its parents.
C)Isaac: I think it depends on the age of the ladybugs. As they get older they add more spots.
D)Fred: I think it has to do with the sex of the ladybug. Males will add more spots to compete for the females.
E) Andrea: I think it depends on what each ladybug was born with.
F) Alice: I think they change their number of spots when there is a need for them to do so.
Explain your thinking. Describe your ideas about why the ladybugs look different.

If a cell in G1 phase has 4 chromosomes, how many chromosomes will it have by the end of meiosis?
Answer:
G1 phase (Gap 1) - Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) - Each of the 46 chromosomes are duplicated by the cell. III.

Consider that basilosaurus lived in the ocean, how has the environment of this location changed since basilosaurus lived?
Answer:
Explanation:
This is because basilosaurus lived in the aquatic region with it sturdy slippers and long body.There was change in the environment due to the shifting that occur to tectonic plates and marking a portion of the land to move to a higher altitude or block the inflow of water from being in the deserted place.

In the oldest fossils found in Bitter Springs (Cyanobacteria), why can we only find the remains of single celled organisms
Answer:
Due to presence at early days of the planet.
Explanation:
We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.

A dog, a human, and an ant all use their legs for locomotion. Which statement(s) below accurately characterize the evolutionary
relationship between these species? Select ALL that apply.
Answer: B,C, and E
Explanation:
All the following apply:-
Legs are homologues between the human and dog , but analogues in the ant.
Humans and dogs have more recent common ancestor then the dog and the ant
DNA sequence comparison for the human and the dog will show greater homologue than between the dog and ant.
What are homologues organs?
These are the organs which are anatomically similar but differ in function.
What are analogues organs?
These are the organs which are anatomically different but functionally similar
Hence the B), C) and E) are correct option.

How does the attachment of spindle fibers differ between mitosis and meiosis I?
In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
WHAT IS MITOSIS AND MEIOSIS?
Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.WHAT IS SPINDLE FIBER?
Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division). During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

A human cell that has 46 chromosomes would have __ daughter cells that each have __ chromosomes after mitosis.
Answer:
2 daughter cells, 46 chromosomes
Explanation:
Mitosis is reproduction of somatic cells, or body cells. It's end product will always be 2 daughter cells, each identical to one another, therefore meaning, it will also have the same number of chromosomes!
Answer: one daughter cells and each have 23
Explanation: mitosis is the first then meiosis
People who have leukemia, a cancer that affects white blood cells, are often given Cytarabine. This drug inhibits the synthesis of DNA. Which phase of the cell cycle is most affected by Cytarabine?
A
Interphase
B
Cytokinesis
C
Prophase
D
Anaphase
Answer:
I think interphase because fna synthesis happens within the s-phase of the cell cylce and 5he s phase is suring interphase and not mitosis
The phase of the cell cycle which is most affected by Cytarabine is the Interphase. Thus, the correct option is A.
What is the cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The entire cell cycle can be divided into two phases.
The InterphaseThe M-phase (division phase).As per the question, the drug Cytarabine inhibits the synthesis of DNA, it definitely inhibits the interphase of the cell cycle. This is because the synthesis of DNA occurs in the S-phase of the cell cycle which is a substage of the interphase.
Therefore, the interphase of the cell cycle must be affected by the drug Cytarabine. Thus, the correct option for this question is A.
