22. Why do you think the sea urchin was chosen to test the effect of changes in pH?
Answer:
as it settles deeper underwater ph tends to be higher and a sea urchin tends to be more resilient to change
Acidic seawater, at current pH levels found in the world's oceans, can have a negative impact on sea urchin larval development so it is taken to test the effect of changes in pH.
What is sea urchin?Sea urchins are spiny, globular echinoderms of the Echinoidea class. The urchins were able to compensate for internal pH in modest acidification (pH 7.8) and not in higher acidification (pH 7.6).
The pH of coelomic fluid was lower at higher temperatures.
Thus, due to this, the sea urchin was chosen to test the effect of changes in pH.

Question 10 options:
Specialized cells have specialized DNA that allows them to produce specialized proteins needed by an individual cell
The brain sends mRNA as a messenger to specific cells telling them to send proteins to copy DNA from the ribosomes so other cells can get a copy of those genes.
Every cell in the body contains the entire DNA genome. Specialized cells turn on specific genes to make specific proteins, which are then released for use throughout the body.

Show different life cycle patterns with the help of near labelled diagram
Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?
Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:

environmental pressure definition
Environmental pressure, also known as selection pressure or ecological pressure, refers to the influence exerted by the environment on living organisms, driving the process of natural selection.
It encompasses various factors, such as climate, competition for resources, predation, and other ecological interactions.
Environmental pressure plays a pivotal role in shaping the characteristics and traits of organisms within a population.
Individuals possessing advantageous traits that align with the environmental conditions are more likely to survive, reproduce, and pass on these beneficial traits to the next generation.
Over time, this process leads to the adaptation and evolution of species, enhancing their ability to thrive and succeed in their specific ecological niches.

What kinds of organisms use anaerobic respiration?
Answer:
Certain prokaryotes, including some species of bacteria and Archaea, use anaerobic respiration.
Explanation:
For example, the group of Archaea called methanogens reduces carbon dioxide to methane to oxidize NADH. These microorganisms are found in soil and in the digestive tracts of ruminants, such as cows and sheep.
organisms are classified as either prokaryotes and eukaryotes.which of the following do the cells of all prokaryotes and eukaryotes contain?
Answer:
Prokaryotes contains a single chromosome and DNA whereas eukaryotes contain true nucleus and organelles.
Explanation:
The cells of all prokaryotes contains a single chromosome and a double-stranded DNA while on the other hand, nucleus and other organelles are absent whereas eukaryotes contain true nucleus and organelles such as golgi bodies, endoplasmic reticulum, lysosomes, ribosomes, vacuole and mitochondria. True nucleus means the membrane is present around the nucleus.

what would happen if igneous rock was first exposed to the energy from the and then millions of years later to energy from earth's interior?
Answer:
If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground.
Explanation:
Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contains fossils

Answer:

The symbiotic relationship is a type of relationship in which two organisms living with each other and gives benefit to one another.
Mutualism is a type of symbiotic relationship in which both organisms benefited from one another. In this type of relationship, one organisms is smaller that lives inside the body of other big organisms.
For example, bacteria lives in the nodules of plant's root. The plant provides shelter to the bacteria while on the other hand, bacteria fixes atmosphere nitrogen into available form so in this way both get benefits from one another.

A. completing a full sequence of human DNA (the Human Genome Project) B. identifying the regions of human DNA that are transcribed into RNA C. identifying the regions of human DNA that bind to proteins D. analyzing the regions of human DNA that vary among individuals E. describing the molecular structure of human DNA
Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.

Use your knowledge of osmosis to explain why the mass of each cube increased.
Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass
The mass of each potato cube increased because they have gained water by osmosis.
Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.
A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).
Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.
