An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit ______ as a larva and ______ as an adult. bilateral symmetry . . . bilateral symmetry bilateral symmetry . . . be asymmetrical radial symmetry . . . radial symmetry radial symmetry . . . bilateral symmetry bilateral symmetry . . . radial symmetry
Answer:
Bilateral symmetry as a larva
Radial symmetry as an adult
Explanation:
Bilateral symmetry refers to the division of the animal through a longitudinal plane, int two mirror-image, right and left halves, as seen in organisms such as insects, reptiles or in man. Animals with bilateral symmetry have anterior and posterior halves (head and tail), dorsal and ventral (front and back), and right and left sides. Most animals are bilaterally symmetrical. Animals with bilateral symmetry are best suited for active lifestyles involving streamlined and directional motion.
Radial symmetry refers to the arrangement of body parts around a central axis, just like rays on a sun, ie.they have bodies that seem to radiate outwards from a central point. Animals that are radially symmetrical have top and bottom surfaces only but no left and right sides, or front and back sides. Animals that have radial symmetry are best suited for sedentary lifestyles and are usually attached to some surface (sessile)
An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit bilateral symmetry as a larva and radial symmetry as an adult.

A segment of a DNA strand is shown. AGGTCAGG
a. What is the complementary DNA strand?
b. What is the mRNA strand?
c. What amino acids are produced as a result (use the codon chart to help you)
Answer:
b. messenger ribonucleic acid
a. The complementary DNA strand is the sequence that pairs with the given DNA strand. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary DNA strand of "AGGTCAGG" would be "TCCAGTCC".
b. The mRNA strand is synthesized based on the complementary DNA strand. In mRNA, thymine (T) is replaced by uracil (U). Therefore, the mRNA strand corresponding to the given DNA sequence "AGGTCAGG" would be "UCCAGUCC".
c. To determine the amino acids produced, we need to identify the codons (groups of three nucleotides) in the mRNA strand and refer to a codon chart (also known as a genetic code chart). Here's an example of how the codons in the mRNA strand "UCCAGUCC" can be translated:
UCC (Serine)
AGU (Serine)
CCU (Proline)
Therefore, the resulting amino acid sequence would be Serine-Serine-Proline.

Transitional fossil evidence shows intermediate steps in the evolution process. So, the correct option is A.
What do you mean by Fossil?Fossils may be defined as the preserved remains, or traces of remains, of ancient organisms. They are dead and organic remains of past organisms.
Transitional fossil evidence would show intermediate forms of a species and they changed and accumulated adaptations at a slow pace. These are remnants of an organism that came in the version of the current species.
Therefore, Transitional fossil evidence shows intermediate steps in the evolution process.

A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.
In mitosis, the DNA is replicated once, while in meiosis it is replicated twice.
True or False?
Answer:
False
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

what's assembled during the second step of protein synthesis
Answer: Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein. In the first step, called transcription, the genetic code in DNA is copied by RNA. In the second step, called translation, the genetic code in RNA is read to make a protein. A mutation is a change in the base sequence of DNA or RNA.

Which property (quality) of fossils allows scientists to determine the relative ages of rock layers?
A.Fossils show change over time as species evolve.
B.Fossils form from the remains of living organisms.
C.Fossils are usually found only in sedimentary rock.
D.Fossils can be analyzed to determine their exact age
The property (quality) of fossils allows scientists to determine the relative ages of rock layers are fossils show change over time as species evolve.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch. Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
Chemistry is present in this process, more precisely the element Carbon. The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
