The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of answer choices choanoflagellates are animals choanoflagellates are more closely related to sponges than they are to protists choanoflagellates and sponges evolved similar cell structures through convergent evolution choanoflagellates and sponges are sister groups
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

Plant Cell Writing Prompt
Part 2: Using your notes, write a detailed explanation of a plant cell, one of the most complex cells. Please be sure to write at least two paragraphs and highlight all parts used in your writing. Make sure your essay includes all the following parts:
cell membrane, genetic material (DNA), cytoplasm, ribosomes, cell wall, nucleus, rough endoplasmic reticulum, smooth endoplasmic reticulum, Golgi apparatus, a large vacuole, mitochondria, chloroplasts, lysosome.
Answer:
Plant cell
Explanation:
Cell wall: cell wall is only found in plant cell . it is made up of cellulose. it's function is to give shape to the cell and protect the delicate inner parts of the cell. this cell is fully permeable. it means it will allow all substance to pass in. cell membrane is made up of protein and lipids. it's function is to control what comes in and out of the cell. this membrane is selectively permeable. it means it allows some substance to pass in and others don't. cytoplasm is large sac like structure. most chemical process occur here. chromoplast are the green pigments.
cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .

In a scientific investigation, after the question is defined, the next step is most likely which of
the following statements?
A. Collecting the data
B. Formulating a hypothesis
C. Designing the experiment
D. Identifying materials needed
In a scientific investigation, the next step after the question is defined is to formulate a hypothesis. A hypothesis is a testable explanation or a prediction. Therefore, the correct option is B.
What is Hypothesis?A hypothesis is the proposed explanation for a phenomenon. For a hypothesis to be scientific, the scientific method requires one to test it. Scientists generally form hypothesis on the basis of scientific hypotheses of previous observations that cannot satisfactorily be explained with the available scientific theories.
Types of hypothesis include simple hypothesis, complex hypothesis, and directional hypothesis.
After the question has been defined, the next step taken by a researcher is to form a hypothesis, or testable explanation. It is about making predictions based on the hypothesis and further test the prediction.

Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Which phase of the cell cycle is helicase most likely active?
A) S
B) М
C) G1
D) G
Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

O Coral reefs are generally less than ten years old.
o Coral reefs contain a great diversity of life and species.
O Coral reefs cover most of the world's ocean floor.
O Coral reefs contain very few species other than fish.

Explanation:
The following statements about coral reefs are true: "Coral reefs contain a great diversity of life and species." That is the second option, as the coral reefs are among the most diverse and biologically rich ecosystems on the planet.
What is the importance of coral reefs to the ecosystem?The coral reef is a type of structure that forms large, interconnected structures, creating a habitat for a wide range of other species, such as fish, crustaceans, and mollusks, and the reef provides shelter and food for a diverse array of organisms. Coral reefs generally occur in warm waters along the coasts of tropical and subtropical areas, so climate change harms them.

Goodluck. I hope I helped
Explanation:
Oceans support the livelihoods of an estimated 520 million people who rely on fishing and fishing related activities, and 2.6 billion people who depend on fish as an important part of their diet. But Illegal fishing is threatening the food supply of coastal communities as fish populations decline due to overfishing in areas fishers are not permitted to access. Addressing illegal fishing will positively contribute to the equitable growth and empowerment of the people who rely on oceans for food and income.

Pioneer species such as lichen and moss inhabit an area after a major disturbance such as a volcanic eruption. Over time, other species are found in the disturbed area and the number of pioneer species decreases. Why does the number of pioneer species decrease? The amount of available sunlight is reduced. The pioneer species can no longer thrive. ⊝ The area has more soil to support complex plants. The competition increases between organisms. ⊝ The area is more susceptible to the wind. Seeds are captured in the pioneer plants and germinate at a higher rate. ⊝ The temperature is not as extreme as it was following the disturbance. Fewer of the pioneer species reproduce. ⊝ CLEAR ALL ❮ PREVIOUS ... 3 4 5 6 7 8 9 10 11 12
Answer:
The competition increases between organisms.
Explanation:
Primary succession occurs after a disturbance or disaster that leaves open spaces with no living organisms. These new open areas are the case, for instance, of a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. No previous species inhabiting this area are left.
These scenarios allow new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the ground and making it better with time. Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources. Habitat modification keeps on going while new species establish. They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. This sequence continues until there is not more facilitation, and the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
