Identify and describe three mechanisms of movement of lymph through the lymphatic vessels.

Answers

Answer 1

Answer: Lymph fluid can only flow forward through lymphangions due to the closing of valves after fluid is pushed through by fluid accumulation, smooth muscle contraction, or skeletal muscle contraction if that makes sense. Without valves, the lymphatic system would be unable to function without a central pump.

Compare how natural selection selects for organisms with beneficial traits over those with less beneficial traits for an environment.

Answers

so natural selection is the worlds way of saying “you’re better then them”. so pretty much beneficial traits for an organism will be more favorable, with helping them survive, hunt, etc. while less beneficial, or less favorable, will often die off.

Natural selection is the process by which animals adjust to their environments.The environment affects natural selection. Natural selection does not prefer characteristics that are better in some fundamental way.

Natural selection is a process that favors heritable characteristics that boost an organism's chances of survival and enable additional reproduction.

What decides which features are adaptive during the course of natural selection?

In evolutionary biology, we decide which qualities in an organism are adaptive (caused by natural selection) and which are non-adaptive or spandrels by examining whether or not that particular trait was something that arose for its current purpose would be an adaptation.

what are you trying to find??

Part C When a material is heated, the change in temperature depends on the kind of material and its mass. Different objects can absorb and release different amounts of energy when heated and cooled. This property is called heat capacity. How might scientists apply this property to design something useful in the real world? Give one or two examples.

Answers

Answer:

Not really sure about this question but what I think is,

So for example, metal..Metal has a very low specific heat capacity, but we use it pretty much in all our lifetime right? Things that have low heat capacity have very high capacity if that makes sense. Things like water and oil, they take more energy to get heat up or get hot. Its funny because its what makes our planet survivable. 70% of our planet is of course water and radiation (light and heat) from the sun strikes 70% of water. Meaning its not heating anything up so quickly. Hope this somewhat helps you out and gives you an idea on what the question is talking about :) Enjoy!

Explanation:

The pictures of the ecosystems are needed to be put into the simplest -> complex order.

Image 1 could be the simplest as it only has one organism.

Image 3 would be the next simplest as it has only a group of the same organism.

Image 4 would come next as it has aqua life and surroundings but the same fishes!

Image 2 would be the most complex, as it has various biodiversity and surroundings!

The order would go as Image 1 -> Image 3 -> Image 4 -> Image 2.

During his voyage on the HMS Beagle, Darwin observed the
beaks and behavior of finches. These finches were similar
in some ways to the single finch species that existed on
the mainland of South America. On the Galápagos Islands,
however, there were 13 different species, each with
different beaks and different diets. Later, Darwin
hypothesized that natural selection could explain the
differences in the finch species. Many years later,
Rosemary and Peter Grant of Princeton University began to
test Darwin's hypothesis.
Scientists have recently developed a hypothesis based on
evolutionary concepts and the Grants' work. First, finches
from South America arrived on one of the islands. Then,
the finches that arrived on the island had to survive in a
new environment. The plants on the island were different
from the plants on the mainland. As a result, the
population on the island evolved differently from the
population on the mainland.
Later, a few finches from the island may have flown to
another island and begun the speciation process again.
This process may have been repeated many times. Now
there are 13 distinct species.

You go on an expedition into the Amazon Rainforest to look for new species before they are destroyed by logging. You find one organism you have never seen before. You run a few tests to determine what kind of organism it is. You determine that it is multicellular and that it first digests, then absorbs nutrients from the environment around it. What classification fits it best?
A. Plantae
B. Animalia
C. Fungi
D. Protista

Answers

the answer is c fungi fits best

Multicellular is a cellular classification where the organism is made of more than one cell. The multicellular organism that absorbs nutrients best fits in the kingdom of Fungi. Thus, option C is correct.

What is Kingdom Fungi?

Fungi is one of the five kingdoms that are characterized by eukaryotic organisms with multicellular structures. They contain microorganisms that are heterotrophs and cannot make their own food. They absorb the nutrients from decaying organic materials.

The fungal mycelia and filaments called hyphae allow fungi like mushrooms and molds to absorb nutrients and minerals from the surrounding. They digest the nutrients with the help of enzymes.

Therefore, option C. the Fungi first digest then absorb nutrients from the environment.
