A student is given a list of traits and is asked to organize them in a Venn diagram as shown below.
Which traits should the student put in section II (Both)?
1 a scar and blood type
2 tiger's stripes and wolf's social status
3 musical talent and wolf's social status
4 musical talent and skin color
Answer: The correct answer is option B) a scar and wolf's social status.
The acquired traits can be defined as the traits, which are only influenced by the environment of the organism. The acquired trait cannot be passed down to the offspring, as they are not genetically determined. A scar and the social status of any organism is dependent on the behavior of the organism to the environment, no genes code for both of these characters. So, scars and Wolf's social status is an acquired trait.

Sobre la pregunta:
Cucigrama. Pregunta 1 vertical. Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Answer:
Intestino delgado
Explanation:
El intestino delgado es el organi mas largo del tubo digestivo, pudiendo medir 7 metros de longitud y 3 cm de diametro. Se caracteriza por estar sumamente plegado sobre si mismo. La primera porcion, llamada duodeno, recibe secresiones de glándulas biliar y pancreática, y las mezcla con enzimas digestivas. Esta mezcla se encarga de degradar la comida y transformarla en sustancias solubles, como amino ácidos.
Es en el intestino delgado donde ocurre la absorción de nutrientes. Las paredes intestinales estas cubiertas por microvellosidades que aumentan la superficie de absorción.
Las microvellosidades son células que componene el epitelio columnar, y que extienden proyecciones hacia el lumen del organo.

B. the presence or absence of DNA
C. Plant cells would be green
D. Animal cells would contain a nucleus
SORRY FOR THE LITTLE POINT PLEASE ANSWER ITS DUE IN 2 MINUTES
Answer:
I think the answer is A
Explanation:
The presence or absence of a cell wall is examining cells under a microscope.
What is Cell wall?Cell walls are a specific type of extracellular matrix that cover every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.
The cell wall serves a variety of activities that are essential to plant life, despite being frequently thought of as an inert product used only for mechanical and structural purposes.
These include: giving the living cell mechanical defense and a chemically insulated environment; offering a porous medium for the circulation and distribution of water, minerals, and other small nutrient molecules.
Therefore, The presence or absence of a cell wall is examining cells under a microscope.

Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Answer:
Correct
Explanation:
Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.
The Homoeostatic feedback mechanism has three basis components and they are independent to one another.
These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.
So, the order in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.

The cell cycle is the life of the cell from the time it is first formed from a dividing parent cell until its own division into two cells
Explanation:
cell cycle is made up of three main parts: interphase, mitosis, and cytokinesis. Most biologists agree that interphase makes up the period of time that a cell would be preparing for cell division. Cells spend the majority of their lives in this stage. During interphase a cell is going to be growing, replicating its genetic material and essentials to carry out cell division, and proofreading the genetic material to ensure replication has occurred correctly. This doesn’t sound like much, but it’s actually the longest part of the cell cycle. Once this is complete, the cell will then go through cell division and, theoretically, split into two new cells (cytokinesis).
How cytokinesis works will depend upon the type of cell that is dividing. Here is an image that summarizes the differences in cytokinesis in plant cells and animal cells, which is the classic example used in many introductory biology courses:
How are gametes produced?
Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis. ... These cells develop into sperm or ova. The ova mature in the ovaries of females, and the sperm develop in the testes of males.
Answer:
Gametes are produced by Mitosis (not meiosis) and after fertilization a diploid zygote is created. The single zygote cell never grows or divides my mitosis. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.

Suppose that an extreme frost affected an area where the orange orchard is growing. Predict the impacts of this event on the
orange trees. Select ALL that apply.
A)
The trees will undergo mutations that enable them to survive harsher and
colder winters in the future.
B)
This could result in a population bottleneck, where few trees survive,
resulting in lowered genetic diversity
C)
The trees will undergo artificial selection which results in only trees that
are better adapted to freezing temperatures
D)
Trees with the ability to survive the freezing temperatures will reproduce
and create offspring with similar genetic makeup.

Answer:
C
Explanation:
Without decaying wood , the nutrient cycle is unbalanced
Decreased soil fertility by preventing nutrient recycling. Therefore, option (C) is correct.
What is nutrient recycling?Nutrient recycling is the process by which essential nutrients, such as carbon, nitrogen, phosphorus, and sulfur, are continuously cycled through the biotic and abiotic components of an ecosystem. This cycle involves the movement of nutrients from the non-living (abiotic) to the living (biotic) components of an ecosystem and back to the non-living components.
The process of nutrient recycling involves the decomposition of dead organic matter by microorganisms and the subsequent release of nutrients into the soil, water, and air. These nutrients are then taken up by plants and other organisms, which are eventually consumed by other organisms in the food chain. When these organisms die or produce waste, the nutrients are again released into the environment to be used again.
Nutrient recycling is crucial for the maintenance of healthy ecosystems and the sustainability of life on Earth.
