Answer:
B. DR, Dr, Rd, dr
Explanation:
This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.
Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:

Which of the following is true if an organism can reproduce asexually?
A. Offspring are genetically different from the parent.
B. Offspring are genetically identical to the parent.
C. Offspring are genetically identical to the parent only 50% of the time.
D. Offspring are genetically variable.
Answer:
c
Explanation:
i think im not sure
If an organism can reproduce asexually, its offspring are genetically identical to the parent.Therefore, the correct option is B.
What is asexual reproduction?Asexual reproduction is a mode of reproduction in which an organism produces offspring without the involvement of gametes or the fusion of genetic material from two parents.
Asexual reproduction involves only one parent, and the offspring are produced by mitotic cell division, which creates identical copies of the parent's DNA. As a result, asexual reproduction produces offspring that are genetically identical to the parent, and there is no mixing of genetic material from two parents as occurs in sexual reproduction.Therefore, the correct option is B.

Answer: hypothesis, prediction, design experiment, carry out experiment, etc
Explanation:If the question is supposed to be, is there a connection between atmospheric oxygen level and photosynthesis, then the next step would be to frame the hypothesis, which could be, for example,
“photosynthesis requires oxygen”, and a prediction such as,,
in a closed system, photosynthesis will reduce the oxygen level, or even photosynthesis does not proceed without oxygen.
and a format to test the hypothesis (design an experiment)
perform the experiment
collect data
analyse data
(of course, in this case, the data will support the null hypothesis).

State Newton's Law for each Question
1. A secured object in an orbiting spacecraft remains at rest unless acted upon by
A. an electrical force
B. an external force
C. a magnetic force
D. a frictional force
10 POINTSSSSSS
Answer:
B. an external force
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
Hence, a secured object in an orbiting spacecraft remains at rest unless acted upon by an external force.
Why might both cell types be considered equally successful
Answer:

Most sex-linked Gene's are on the ____ chromosome, simply because they are built of much more DNA. However, _____ are more likely than _____ to exhibit sex-linked traits.
Answer: most sex-linked genes are on the X chromosomes because they are larger than Y chromosomes. Males are more likely than females to exhibit sex-linked traits
Explanation:
Males are more likely than females to display recessive traits because a single recessive gene on the X chromosome is often not matched by a Y chromosome allele and therefore expressed.

Jose fears a bioterrorism attack with the Ebola virus but refuses to get a flu shot, even though he is more at risk of dying from the
flu. Jose has what perception
towards risk?
a. optimism bias
b. degree of controltion
c. catastrophe
d. Instant gratification
optimism bias. jose thinks he's immune to the flu, even though he is afraid of diseases in general.
What is Optimism Bias?
The optimism bias is essentially a mistaken belief that our chances of experiencing negative events are lower and our chances of experiencing positive events are higher than those of our peers.
This phenomenon was initially described by Weinstein in 1980, who found that the majority of college students believed that their chances of developing a drinking problem or getting divorced were lower than their peers.
The optimism bias doesn’t mean that we have an overly sunny outlook on our own lives. It can also lead to poor decision-making, which can sometimes have disastrous results.
Therefore, optimism bias. jose thinks he's immune to the flu, even though he is afraid of diseases in general.

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.

In the diagram below, which cells are involved in the process of sexual reproduction? A.) cell 3, only B.) cell 1 only C.) cell 1 and 2 D.) cell 2 and 3
Cell 1 and 2 are involved in the process of sexual reproduction which are sperm and egg respectively.
What are gametes?Gametes are reproductive cells that are responsible for sexual reproduction. In animals and plants, gametes are typically specialized cells that are specifically designed for the purpose of reproducing and transmitting genetic information from one generation to the next. Gametes are produced by the process of gametogenesis, which is the process of forming and developing gametes.
In animals, gametes are typically either eggs (ova) in females or sperm in males. Eggs are large, non-motile cells that contain a large amount of cytoplasm and nutrients to support the development of an embryo. Sperm are smaller, motile cells that are specialized for fertilization and are capable of swimming through the female reproductive tract to reach the egg.
In plants, gametes are typically produced by specialized cells called gametophytes. Gametophytes produce gametes through a process called meiosis, which is a type of cell division that results in the production of four genetically diverse daughter cells. The gametes produced by gametophytes are typically small and non-motile, and they are capable of fusing with gametes from other plants to produce a fertilized egg, or zygote.
