1) Why is embryonic stem cell research controversial?
2) What is a potential source of stem cells that is not controversial?
Answer:
1.) It is controversial because in order to take embryonic stem cells, the embryo must die. This is killing a baby.
2.) Stem cells can be taken from your own body from your blood stem cells. This kind of transplant would be considered an autologous stem cell transplant and could help heal diseased or damaged bone tissue.

What is the best reason for the scientific community to accept a theory? The theory is supported by all the available observations and data. An award-winning scientist proposed the theory. The majority of the general public agrees with the theory. The theory contradicts an older theory.
Answer:
The theory is supported by all the available observations and data.
Explanation:
The scientific community will accept a theory when a sufficient body of evidence supports it. This includes experiments that refute other potential theories. Experiments should also be carried out that attempt to disprove the theory but cannot.
It should not matter who proposed the theory or who supports it, and instead should entirely be based on the quality and abundance of data supporting it.
Answer:
The theory is supported by all the available observations and data.
Explanation:
The picture shows fruit produced by two parents and fruit
produced by one of their offspring.
Which of these best describes this inheritance pattern?
х
O codominance because he fruit color of the offspring is
an intermediate form of the parents' fruit color
O codominance because both parents' colors are
expressed in the offspring
O incomplete dominance because both parents' colors
are both visible in the offspring
O incomplete dominance because the fruit color of the
offspring is an intermediate form of the parents' fruit
color
Answer:
incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color
Sry if I'm wrong, have a nice day.
The given image shows incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color. The correct option is D.
What is incomplete dominance?When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance.
This sort of gene interaction frequently produces an intermediate or distinct phenotype. Additionally called partial dominance.
Two other types of genetic inheritance are codominance and incomplete dominance. It basically means that no allele can prevent or stifle the production of the other allele through codominance.
Incomplete dominance, on the other hand, occurs when a dominant gene does not entirely block the effects of a recessive allele.
Fruit produced by two parents and fruit produced by one of their children are shown in the photo.
Because the fruit color of the offspring is an intermediate version of the fruit color of the parents, it is incomplete dominance.
Thus, the correct option is D.

Answer:

Explanation:
Yeet
Answer:
At this level, students are expected to 'explain the behaviour and properties of materials in terms of their constituent particles and the forces holding them together’ (VELS standards Level 6). However, the fact that students may be able to draw the usual static arrangements of particles in solids, liquids and gases does not mean that they hold a fully particulate view of matter. Research evidence suggests that many students at this age and older still hold a number of alternative conceptions about particles which prove difficult to extinguish. They often lack an appreciation of the very small size of particles, attribute macroscopic properties to microscopic particles, have difficulty appreciating the motion of particles in all states of matter and have problems understanding forces between particles.

What happens when a ecosystem is in equilibrium
In equilibrium, an ecosystem has a balance between all organisms and their needed resources which make them to have ideal living conditions for organisms as well as climate for survival.
What is ecosystem equilibrium?Equilibrium, which is a comparatively steady state that maintains population sizes within a reasonable range, is referred to as a healthy ecosystem (not too many of a certain species alive or dead).
When an ecosystem is in equilibrium, all of the organisms and the resources they require are in balance. The environment also has the right climate for survival and excellent living conditions for creatures. The stability of the environment and the organisms is guaranteed by ecological balance. It fosters an environment that is favorable for organism growth and proliferation.

Answer:
the total amount of matter
Explanation:
In a closed system, the total amount of matter remains the same as it is transferred between organisms and the physical environment, even though its location or form changes.
When one organism consumes another, this matter can change form, but it does not disappear. Eventually, the matter is broken down by decomposers and deposited in the ecosystem's soil, where it can be used by plants. From there, it is able to begin the cycle all over again.

Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin's
work after he returned home from his voyage and studying the selective breeding of pigeons prompted him to ask
which question?
Do living things change over time, and if so, how?
Are the Galapagos finches and those on the mainland the same species?
Are pigeons related to the Galapagos finches?
Can selection in nature also lead to a new species over time?
Answer:
D) Can selection in nature also lead to a new species over time?
Explanation:
The question will be "Can selection in nature also lead to a new species over time?". The correct option is D.
Who was Charles Darwin?English naturalist, geologist, and biologist Charles Robert Darwin is well-known for his contributions to evolutionary biology.
Charles Darwin, a naturalist of the 19th century, investigated the theory of natural selection.
Natural selection provides an explanation for how a species' genetic features might evolve through time. This could result in speciation, or the creation of a new, separate species.
New scientific questions are frequently posed as a result of scientific research.
After his journey, Charles Darwin studied the selective breeding of pigeons and made observations that led him to wonder: "Can selection in nature also lead to a new species over time?"
