Blank 1: <u>hawks and owls</u>
Explanation: Tertiary consumers lie on the top of the food web or pyramid. They are dependent on other organisms for their food. These are carnivores by mode of nutrition. Here, the food web sequence would be like-
small birds----->snakes----->hawks and owls.
That's why they are the tertiary consumers.
Blank 2: <u>decomposers
</u>
Explanation: The organic matter of dead plants and animals is decomposed by decomposers. They breakdown the complex organic compounds into simpler substances.
Answer;
They have revealed new information about cell structure and processes.
Explanation;
-The Cell Theory states that, All living things are made up of cells, Cells are the basic units of structure and function in living things, and that new cells are produced from existing cells.
-Most microscopes use lenses to magnify the image of an object by focusing light or electrons.
-The Invention of the Microscope helped the development of the cell theory because it allowed the scientists to actually discover that everything was made up of cells, and what cells do to come up with that theory. If the scientists did not see that cells existed, they could not have observed the cells easily and they would not be able to construct the cell theory.
Answer:
This question lacks options; the options are:
A) Artificial selection
B) Stabilizing selection
C) Disruptive selection
D) Directional selection
The answer is D) Directional selection
Explanation:
Changes in the environmenal condition affects the distribution of organisms phenotypes. Via this change, organisms with certain traits are naturally selected. The types of natural selection are; stabilizing, disruptive and directional.
Based on the description of the selection in this question, the type of selection is DIRECTIONAL. Directional mutation is that in which one of the two extreme phenotypes in a population is selected against while the other is favored by the occurrence of a natural environmental hazard. The distribution gradually shifts to favour one extreme over the other until the other unselected extreme gets extincted.
This is the case regarding a population of finches affected by drought caused by flood causing all their food source to disappear leaving only ant hills that certain finches with thin beaks can access. This environmental change favorably selects one extreme phenotype (finches with long thin beaks). Hence, a type of DIRECTIONAL selection
Answer:
1. Cartilaginous joints
2. Freely movable (Synovial) joints
3. Temporomandibular joint
4. Arthritis
5. Synchondrosis
Explanation:
1. Cartilaginous joints are those who permits some movements but provide less stability that immovable joint, these joints are slightly movable.
2. Freely movable joints are synovial joints. These joints have a joint cavity between connecting bones, and allow for greater mobility. However, they are less stable than fibrous and cartilaginous joints. For example: elbow.
3. Temporomandibular joint is a like a hinge and a ball and socket joint at the same time. It is a simple hinge that permits to chew.
4. Arthritis is a term that describes inflammation in joints. Some of them include: rheumotaoid arthritis, psoriatic arthritis, etc.
5. Synchondrosis is a joint in which the articulating surfaces are close together but are bound by a hyaline cartilage, which can converts to either bone o fibrocartilage.
The question is asking to choose the following process could the breeder use to determine if Sam is the father of the pups and in my further research and in my own understanding, I would say that the answer would be Y-Chromosome Analysis. I hope you are satisfied with my answer and feel free to ask for more
