Since they lack adaptations for life in water, animals born on land usually need to learn how to swim.
Why are adaptations?Adaptations are special features and modifications in structure of an organism which helps the organism to be better suited to survive and reproduce in its environment.
All organisms have features that help them survive in their environment.
Land organisms usually have feet to walk on land.
Aquatic organisms have parts that help them swim in water.
Therefore, based on adaptations to their habitat, animals born on land usually need to learn how to swim.

In a math class with 25 students, a test was given the same day that an assignment
was due. There were 15 students who passed the test and 16 students who completed
the assignment. There were 6 students who failed the test and also did not complete
the assignment. What is the probability that a student who completed the homework
passed the test?
We can confirm that the probability of a student who completed the assignment receiving a passing grade is above 90%.
How can we calculate this probability?We can arrive at this number with the information given to us. We are told that of the 16 students who successfully completed the assignment, 15 received passing grades. By dividing this number we can find the percentage of these students that passed, and this serves as the probability, which results in roughly 93%.
Therefore, we can confirm that the probability of a student who completed the assignment receiving a passing grade is above 90%.

Answer:
I believe the scientific property referes to the composition, on an atomic level, of an element or compound. It's property(ies) are what constitutes the element in an isolated state, but also how it reacts to changes in environment: (temperature, humidity, etc..); but also how it reacts to other elements. What changes occur and if it has the potential to change it's molecular "structure".

Which process depends on binding between specific molecules on both the host and pathogen, so that the pathogen can gain a stable foothold on host tissues
Adhesion depends on binding between specific molecules on both the host and pathogen so that the pathogen can gain a stable foothold on host tissues.
What is adhesion?In epidemiology, adhesion makes reference to the process in which pathogen and host interact during an infection.
The adhesion process is fundamental to reach the survival of the pathogen during a particular infection.

You are comparing the events of meiosis I in cells from several different organisms. You come across one species in which you do not observe any chiasmata. The best conclusion to make is
The best conclusion to make if no chiasmata is observed in a species is that crossing over does not occur in that species.
What is chiasmata?Chiasmata is the contact point between the two chromatids of a chromosome during the prophase stage of meiosis.
Chiasmata forms during the process of crossing over in meiosis, where sister chromatids of non-homologous chromosomes exchange genetic material.
According to this question, the events of meiosis I in cells from several different organisms is being compared. However, no chiasmata was observed in a particular species.

In some traits, different phenotypes result from genes whose alleles each contribute a specific increment to the whole. The phenotypes then have a ________ phenotypic distribution.
Answer:
Bill nye the science guy
Explanation:
cuz
The phenotypes then have a different phenotypic distribution.
What is phenotypic distribution?The variation between genotypically identical individuals as well as the average differences between genotypes determines the phenotypic distribution of a trait.
However, each is a result of the succession of habitats in which the creatures grow and thrive.
Across environmental gradients, phenotypic distribution within species can vary greatly, but predictions of species responses to environmental change frequently presumptively assume that species react uniformly throughout their ranges.
Therefore, different phenotypes are caused by genes whose alleles each add a particular increment to the total in some traits. The distribution of the phenotypes changes as a result.

Which choices describe a characteristics of a species that is likely to become invasive?
Select all that apply.
A. thrives near human developments
B. tolerates a range of environments
C. highly specialized
D. reproduces rapidly
A. thrives near human developments
B. tolerates a range of environments
D. reproduces rapidly
The choices that describe the characteristics of a species that is likely to become invasive are that it thrives near human developments and reproduces rapidly, which are in options A and D.
What is an invasive species?Human activities such as land use changes, construction, and transportation can create disturbed habitats that may be more suitable for certain non-native species. Non-native species that are able to thrive in these disturbed habitats have a higher chance of establishing themselves and becoming invasive. Rapid reproduction is a characteristic that allows a species to quickly establish a population and outcompete native species for resources. This can lead to a population explosion and the dominance of the ecosystem by the invasive species. For example, zebra mussels are a non-native species that reproduce rapidly, with each adult female producing up to one million eggs per year.
Hence, the choices that describe the characteristics of a species that is likely to become invasive are that it thrives near human developments and reproduces rapidly, which are in options A and D.
