Answer:
All life as we know it contain DNA/RNA and protein. Fossil records and extant species all prove this fact. The genetic material's inherit ability shows how that the DNA of all creatures, both living and dead, can be traced back to a single point, which is our common ancestral origin of life.
Answer: Almost all genes in microorganisms, plants, and animals have the same codons.

What do oestrogen and progesterone do in the menstrual cycle
Answer:
Oestrogen and progesterone in the control of the menstrual cycle. Progesterone maintains the uterus lining (the thickness of the uterus wall). If the egg has not been fertilised, the corpus luteum dies and progesterone levels drop. This causes menstruation, where the uterus lining breaks down - this is known as having a period.

B- Hair cells of mule contains ______ chromosomes.
C- Type of cell division which produces gametes: _____
Answer:
A-32 B.63 C. Meiosis
Explanation:
A. Gametes has haploid [half] number of chromosomes.
B. The gametes from each organism has haploid number of chromosomes and during gametogenesis this gametes fuse to form 63 chromosome which is for the new organism-the mule.

What type of plate boundary is illustrated in the image?
The type of plate boundary illustrated in the image is convergent boundary plates.
What is the convergent boundary?An area where two plates converge is referred to as a convergent border. The borders of one or both colliding plates may bow up into mountain ranges as a result of the impact, or one plate may bend down into a deep undersea trench.
Convergent boundary plates are the kind of plate border that is depicted in the image. The edges of a plate boundary are those of two plates that are either colliding, moving apart or meeting.
Activities like mountain-building, earthquakes, and volcanoes do happen at plate borders.
Therefore, the border where two plates are colliding is known as a convergence boundary.

When building a spacecraft what are the 3 things NASA is most concerned about?
Answer:
If the ship is strong enough to support the launch. If the ship can withstand high pressure and temperature rates. If the material is resistant and light at the same time.Explanation:
When a spacecraft is built, many tests must be carried out over the years to prove that the spacecraft has the ability to launch into space and fulfill its mission efficiently. In addition to supporting the launch, these ships need to be built in a way that will withstand space conditions that are very different from terrestrial conditions.
For this reason, there is a concern if the ship can withstand extreme situations of temperature, pressure, gravity, weight, among others. In summary, we can say that three of the biggest concerns that NASA has in building spaceships are:
If the ship is strong enough to support the launch. If the ship can withstand high pressure and temperature rates. If the material is resistant and light at the same time.is flowering patterns independent or dependent
Answer:
The correct answer is dependent.
Explanation:
A variable whose variation does not rely upon that of another is known as the independent variable. An independent variable is modified or monitored within an experiment to examine the influence on the dependent variable. On the other hand, the variable that is being measured and examined within an experiment is termed as the dependent variable.
The flowering pattern is being considered as the dependent variable as the pattern of flowering relies upon the concentration of light exposed by the plant.

What is a genotype and what is a phenotype? Also what are dominant and recessive alleles and how are they written out?
Answer:
An organism's genotype is its specific combination of alleles for a given gene. ... The phenotype is the physical manifestation of an organism's allellic combination (genotype). For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible.
Explanation:
How many valence electrons are in an atom of each element in Group 15 in the periodic table?
Answer:
5 valence electrons.
Explanation:
Group 15 can also be called group 5A, meaning that elements in this column contain 5 valence electrons.
The periodic table's Group 15, often known as the Nitrogen Group, contains elements that have five valence electrons.
Nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi) are among the elements that make up group 15. The 2p orbital is where the valence electrons of these elements are situated.
All Group 15 elements, with the exception of nitrogen, which has only 3 valence electrons, have 5 valence electrons since the valence shell can only accommodate a maximum of 8 electrons.
These elements can easily establish covalent connections with other elements thanks to their five valence electrons.
Thus, this characteristic helps explain their chemical reactivity and capacity to create a wide range of chemicals.

A trait that helps an organism to survive and reproduce is called an...
a. Adaptation
b. Allele
c. Variation
d. Selection
Answer:
Adaptation
Explanation:
a change or the process of change by which an organism or species becomes better suited to its environment.
A trait that helps an organism to survive and reproduce is called adaptation. The correct option is a.
What is adaptation?An organism can survive under adverse environmental conditions by changing its shape, physiology, and genetic makeup through the process of adaptation. This happens as a result of natural selection and evolution.
An organism is said to be adapting when it makes changes in response to its environment. These changes help organisms to survive in extreme conditions.
In biology, adaptation is the process by which a species adjusts to its environment; it results from natural selection operating over many generations on heritable variation.
Therefore, the correct option is a. Adaptation.

What are two reasons bees are important beyond making honey
Answer:
Bees are perfectly adapted to pollinate, helping plants grow, breed and produce food. They do so by transferring pollen between flowering plants and so keep the cycle of life turning.
The vast majority of plants we need for food rely on pollination, especially by bees: from almonds and vanilla and apples to squashes. Bees also pollinate around 80% of wildflowers in Europe, so our countryside would be far less interesting and beautiful without them.
Answer:
bees provide air and food but 1 third of all food we eat comes from bees
