Answer:
The factors that might affect the likelihood a species will migrate from the mainland to an island are the distance to the mainland and the island´s size.
Explanation:
Ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could inhabit an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance to the mainland and the island´s size.
At the same time, these factors affect immigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those located farther from the mainland. This is the effect of distance.
The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

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.

Coat color in cats is a codominant trait and is located on the X chromosome. Cats can be black, orange, or calico. A calico cat has black and orange splotches. In order to be calico, the cat must have an allele for the black color as well as an allele for the orange color. Also located on the X chromosome of a cat is a gene that codes for deafness. The gene is recessive. A black female cat that is heterozygous for deafness (Dd) is crossed with a male orange cat that is not deaf. Show the cross. What are the phenotypes of the offspring and in what proportion? (Hint: Place two superscript letters on the X chromosome in your cross.)

Mary has always been very healthy. Even though all her friends have been verysick with the flu this year, she does not feel like she
needs to get a flu shot. Mary has what perception towards risk?
a. degree of control
b. instant gratification
c. optimism bias
d. catastrophe
Optimism bias is the perception towards risk that Mary has.
The optimistic bias is a term to refer to the human tendency to see the future positively and better compared to the past and the present. The optimistic bias includes the tendency to underestimate the possibility of negative things happening, such as illness, car accidents, and unemployment.
According to the above, Maria has a perception of optimistic bias because she is underestimating the possibility of getting sick even though all of her friends have gotten sick. This may be reinforced by the fact that she is in good health and that is why she does not think it is necessary to get vaccinated.
Additionally, the degree of control, instant gratification, and catastrophe options are not correct options because they are types of perception different from optimistic bias.

Why do you think sustainable development has only recently been proposed as a goal for society?
Answer:
Sustainable development is a current trend through which economic development is sought without compromising the environment or natural resources, both in the present and in the future. This concept began to be developed today, since the concept of scarcity of essential natural resources, especially water, oil and certain minerals, which are in an advanced stage of scarcity, is recent.

a. Substitution
b. Insertion
c. Deletion
Answer:
Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:
a. Substitution: GGAUUC → GGAAUC
b. Insertion: GGAUUC → GGACCUUC
c. Deletion: GGAUUC → GG_UC
Explanation:
The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA
Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence. GGAUUC → GGAAUC Mutated DNA: CCTTAGInsertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule. GGAUUC → GGACCUUC Mutated DNA: CCTGGAAGDeletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule. GGAUUC → GG_UC Mutated DNA: CC_AGEach of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.

Which of the following describes the amount of organic material that is available for transfer to the next trophic level after subtracting material
used for respiration?
Biomass
Gross Primary productivity
Net Primary productivity
Primary productivity
Answer:
Net Primary productivity
Explanation:
In an ecosystem, primary productivity is a term used for autotrophic organisms. It is the process by which these organisms like plants, green algae etc. make their own food using inorganic sources. However, they do not utilize all the matter they make from this process.
The NET PRIMARY PRODUCTIVITY (NPP) is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration. This means that NPP is the amount available after removal of the one to be lost via respiration i.e. NPP = GPP - respiration.
Question: "Which of the following describes the amount of organic material that is available for transfer to the next trophic level after subtracting material?"
Answer: "Out of the options given prior to the question, Net Primary productivity is the best choice. The answer alone can be determined through the definition of the word. Net Primary productivity literally is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration. Hence, the correct choice is C."
ways in which seed dormancy can be broken
Answer:
Seed dormancy is defined as the process in which seed are prevented from germination even though environmental conditions are favoring.
There are several ways in which seed dormancy can be broken. Some of them are as following:
Scarification: scarification is a mechanical technique to breakdown the seed dormancy. In this technique, hard seed coat is removed from the seed under cold temperature.
Hot water treatment: The seed is kept into hot water between the 75 degree to 100 degree, that helps in removal of seed coat and allow germination of plant.
Sodium hypochlorite solutions: sodium hypochlorite (NaOCl) solution breakdown the seed dormancy by decomposing germination inhibitors, increases α-amylase activity and scarifying the seed coat.
Hence, three ways to break seed dormancy are Scarification, Hot water treatment, and Sodium hypochlorite solutions.

The Eocene period exists in Earth’s history around 34 MYA.
What could a scientist do to determine what era the Eocene period belongs to on the geologic time scale?
learn what happened during Precambrian time
study information related to the Cenozoic era
view the timing of events in the Mesozoic era
research events that happened during the Paleozoic era
Answer:
B
Explanation:
took the test
To determine what era the Eocene period belongs to on the geologic time scale, a scientist could study information related to the Cenozoic era. The correct option is B.
What is the Cenozoic era?The Cenozoic Era, which began 66 million years ago and continues today, is the most current era in the geological timescale. This era is known for the development of mammals, birds, and flowering plants. It is divided into three epochs: the Paleogene, the Neogene, and the Quaternary.
The Eocene period occurred during the Paleogene epoch of the Cenozoic era. The Paleogene epoch began 66 million years ago and ended 23.03 million years ago, and was followed by the Neogene epoch, which lasted from 23.03 million to 2.58 million years ago.
Therefore, a scientist could study information related to the Cenozoic era to determine the era to which the Eocene period belongs on the geological time scale.
Therefore, the correct option is B.
