An elementary school science teacher decided to liven up the classroom with a salt-water aquarium. Knowing that salt-water aquaria can be quite a hassle, the teacher proceeded stepwise. First, the teacher conditioned the water. Next, the teacher decided to stock the tank with various marine invertebrates, including a polychaete, a siliceous sponge, several bivalves, a shrimp, several sea anemones of different types, a colonial hydra, a few coral species, an ectoproct, a sea star, and several gastropod varieties. Lastly, some vertebrates - a parrotfish and a clownfish - were added. She arranged for daily feedings of copepods and feeder fish.
The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that by providing live copepods (2 mm long) and feeder fish (2 cm long) the dietary needs of all of the organisms would be satisfied. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)?
1. sponges
2. coral animals
3. bivalves
4. sea stars
5. shrimp
Answer:
sponges
Explanation:
because sponges need photosynthesis in order manufacture their food
The organisms namely sponges and coral animals are most likely to starve to death in the lack of photosynthetic endosymbionts. The correct option is 1 and 2.
What are endosymbionts?Endosymbionts are organisms that live in close proximity to another cell or organism.
As sponges are predominantly filter feeders, consuming detritus, plankton, viruses, and bacteria. They also absorb nutrient solution from water directly through their pinacocyte cells.
Due to the lack of photosynthetic endosymbionts the organisms namely sponges and coral animals are most likely to starve.
Thus, the correct option is 1 and 2.

A Three-leaf clover is dominant (T) to four leaves (t). What is the probability of an offspring having 4 leaves when you cross a heterozygous clover with a four-leaf clover?
O 25%
O 50%
O 75%
O 0%
Answer:
%50
Explanation:
Heterozygous = 2 different alleles (Tt)
4 leaf clover = 2 recessive alleles (tt)
T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves
For a recessive trait (four leaves) to show 2 recessive alleles are needed
To find the percentage of the offspring to have four leaves a punnet square should be created
To find the percentage divide the number of four leaf offering with 4 and multiply by 100
2÷4×100=50
= 50%

analyze the negative impacts of estracting land resources, Choose
one of the negative impacts and connect it to how it could negative
impact you in your everyday life,
Answer:
Soil degradation, water shortages, biodiversity loss and global warming.
Explanation:
The negative impacts of extracting land resources are soil degradation, water shortages, biodiversity loss and global warming etc. Global warming greatly influence our daily life because this Global warming changes the climatic condition of the region by increasing the temperature. Using extracted fossil fuels in vehicles releases a lot of carbondioxide gas that collects in the atmosphere and block the sunlight which increases the surrounding temperature. This increase in the surrounding temperature causes floods and greatly impact our life.

The option C "zygous" is not a phenotype.
What is a phenotype?Phenotype refers to the physical and observable characteristics of an organism, which are determined by its genotype and influenced by the environment.
Examples of phenotypic traits include height, eye color, hair color, skin color, and other observable features that vary between individuals of the same or different species. Phenotypes can also include physiological traits, such as blood type, or behavioral traits, such as personality traits in humans.

A male deer tries mating with a female and is chased off by another male, but the original male finds another mate.
The grass that a rabbit usually eats is hard to find one season, but the rabbit finds another temporary food source.
Frogs and their young have coloration that enables them blend in to their environment so they can sneak up on prey.
Birds help take care of each other's young to increase their chances of survival, and the behavior is passed on to offspring.
Birds help take care of each other's young to increase their chances of survival, and the behavior is passed on to offspring.
What is an adaptive social behavior?Adaptive social behavior refers to actions or behaviors exhibited by individuals or groups that enhance their survival or reproductive success. In this case, the birds engage in cooperative parenting, where individuals assist in raising the offspring of others within their social group.
By providing care to the young of other birds, they increase the chances of those offspring surviving and passing on their genes. This behavior benefits the overall reproductive success of the group and is likely to be passed on to future generations, as it contributes to the survival and well-being of the species.

Summarize the different concepts of a species
The concept of species is an important but difficult one in biology, and is sometimes referred to the "species problem".
Thus, Some major species concepts are, Typological (or Essentialist, Morphological, Phenetic) species concept. Typology is based on morphology/phenotype.
The biggest group of organisms that can generate fertile offspring, often through sexual reproduction, from any two individuals of the appropriate sexes or mating types is referred to as a species in biology. It is a unit of biodiversity as well as the fundamental classification and taxonomic rank of an organism.
A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chronospecies idea.
There are between 8 and 8.7 million different species of eukaryotes, according to the most recent accurate estimate.

Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity in the neighborhood you chose.
Hello. You have not shown the neighborhoods to which the question relates, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The best way to reduce spending on carbon dioxide and increase biodiversity in a neighborhood is to provide tree planting through urban afforestation. A well-wooded neighborhood, it has a lower concentration of carbon dioxide because the plants absorb this gas releasing oxygen in place. In addition, some animals such as birds would attract them, in addition to promoting fruit and shade for the neighborhood.
Answer:
The most ideal way to lessen spending on carbon dioxide and increment biodiversity in an area is to give tree establishing through metropolitan afforestation. A well-lush area, it has a lower centralization of carbon dioxide in light of the fact that the plants assimilate this gas delivering oxygen set up. Likewise, a few creatures, for example, birds would draw in them, as well as advancing products of the soil for the area.

What is cosmic microwave background radiation?According to the theory of the Big Bang, the cosmic microwave background is an electromagnetic radiation that is a relic from an earlier stage in the development of the universe. This radiation is also known as "relic radiation." The Cosmic Microwave Background (CMB) is the weak radiation that permeates all of space.
One of the primary confirmations of the Big Bang is thought to be its discovery and thorough studies of its attributes. The cosmic background radiation was accidentally discovered in 1965, which shows that the early cosmos was dominated by a radiation field with extraordinarily high temperatures and pressure.

Mutation is the reason for the more DNA in Calix's cells.
Calix's cells having more DNA than a normal cat because of the mutation in the genes. There is no other way through which DNA in a gene increases. This increase in DNA from a normal condition leads to cancer and other disorders.
Mutation occurs in an organism when they are exposed to radiation which damaged the DNA of that organism so we can conclude that mutation is the reason for the more DNA in Calix's cells.
