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.
Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.
Answer:
la selección natural es el mecanismo principal por el cual la evolución ocurre
Explanation:
Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

2. Which explanation for the increase in genetic diversity of this red panda population is supported by this data?
(1 point)
Red pandas in this population have encountered new predators due to the increase in deforested land, and this new predation pressure has selected for different adaptations.
Red pandas in this population have increased the number of cubs birthed by each mother every year, and this increase in population has resulted in more genetic diversity.
Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
Red pandas in this population have started eating a new diet due to the increase in deforested land, and the new dietary conditions have selected for different adaptations.
5. Which of the following scenarios would reduce the number of inheritable traits in a population, causing the individuals in that population to remain very similar to one another?(1 point)
A swamp that is being drained in order to build houses.
A forest that is being converted into farmland.
A lake that is drying up due to shifts in river flow.
A desert that has existed for millennia.
Answer:
2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
5. D - A desert that has existed for millennia.
Explanation:
2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.
5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.

Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?
A. The insect develops slightly shorter or longer abdominal legs.
B. The insect develops normal body parts at either a slower or more rapid rate.
C. The insect develops normal body parts but in an altered time sequence.
D. The insect develops legs in other parts of its body.
Answer:
D. The insect develops legs in other parts of its body.
Explanation:
HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.
Identify how information for specifying the traits of an organism is carried in the DNA.
Answer: DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Explanation:
The traits or characters are present in the DNA in the form of genes. Genes are short stretches of nucleotides present in DNA and represent the encoded message that is present in the individual.
What is a gene?Genes are present in the DNA. It carries information about the traits that are expressed in an individual. Genes come from parents to offspring, so they are hereditary and pass from one generation to the next. From DNA, mRNA is formed from the gene by the process of transcription.
This mRNA is again converted to proteins or polypeptides by the process of translation. This product is the result of the message that is present in the gene. Example: melanin pigment and skin color variation. As different persons have variations in their genes, the production of this melanin protein synthesis varies, and as a result, skin color among individuals varies.
Hence, the information for specifying the traits is carried by genes present in DNA.

Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.

WILLL GIVE BRAINLIST!!! Suppose mechanical weathering breaks a rock into pieces. How would this affect the rate at which the rock weathers chemically? How do chemical and physical weathering differ? Explain your answer in at least 3 sentences.
Answer:
Explanation:
Mechanical weathering increases the rate of chemical weathering.
As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.
Chemical weathering is different from mechanical weathering(physical weathering ) because the rock changes, not just in size of pieces, but in composition.
That is, one type of mineral changes into a different mineral.
Chemical weathering works through chemical reactions that cause changes in the minerals.

Which statement best describes the relationship between ocean co2 and ph
Acidity rises and pH falls as carbon dioxide levels rise. The correct option is C.
What is ocean pH?A change in the characteristics of ocean water known as ocean acidification may be detrimental to plants and animals.
Scientists have noticed that the ocean's acidity is rising as a result of the water's absorption of atmospheric carbon dioxide.
Ocean acidification is the decrease in the ocean's pH level. The average pH of the ocean's surface fell from about 8.25 to 8.14 between 1751 and 2021.
Ocean water is more basic than drinking water because it is resistant to pH fluctuations due to the presence of various weak acids and their corresponding bases, or buffers.
The ocean is regarded as having a pH that is slightly alkaline. Acidity and pH both drop when carbon dioxide levels rise.
Thus, the correct option is C.

In 1989, a tanker carrying oil struck a reef and spilled 11 million gallons of oil in an
Alaskan bay. The oil not only spilled into the harbor, but also washed up on the
shoreline. The spill killed millions of fish, birds that lived on the shore, sea otters,
porpoises, seal lions and many whales. Every form of life in the area was affected.
Scientists have carefully studied the area and its species since the initial spill to
determine both short-term and long-term effects.
Which of the following was affected the least by this catastrophic event? A: Plants along the shoreline B: Fishermen in the area C: Migratory sea birds D: Crustaceans that lived on the bottom of the bay
Answer:
The answer is C: Migratory sea birds.
Explanation:
Sea birds that are migrating would not only just fly above the spill and nestle on the trees, but they could eat crabs and other animals that scurry around on the shore as a food source due to the death of their primary source of food, fish.
