Answer:
The answer is option D "Machines have replaced much of the manual labor once needed to run a farm."
Explanation:
* Progress in Engineering: This simply means how technological machines like heavy tractors which are now used and are helpful in farming are evolving, meaning they are being used in a larger quantity now.
* Natural Environment: This is the normal way of life or doing things which individuals find themselves practicing in a particular society and at a particular point in time.
* As a result of the machines being developed as an Engineering progress which serves the work of people on the farms, there tends to be less manual labor that would be initially required to run a farm. The machines are now serving the work of human beings (laborers) now.
Complete question:
Which organisms are secondary consumers in a temperate coniferous forest? Select all that apply:
Answer:
The lynx and the wolf are the only secondary consumers on the list.
Explanation:
In the trophic web, the energy transference occurs when each organism feeds on the preceding link and is eaten by the following link.
The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.
The following links are the consumers: herbivores are primary consumers and feed on producers. <u>Carnivores are secondary consumers and feed on herbivores</u>, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.
On the other hand, the moose and the elk, are both first consumers.
A. Plants use capillarity to move water from their roots to their leaves.
Answer:
Flat worms belong to Phylum- Platyhelminthes as they have flat body because they don't have any coelom in their body or called acoelomate
Explanation:
Coelom is called as the true body cavity that is found in Porifera and Cnidaria but when it comes to platyhelminthes, the coelom is not found and thus they have flat like structure and they are categorized under first triploblastic animals that is they contain 3 tissue layer which are found in higher animals (Ectoderm, Mesoderm and endoderm) also cephalization takes place in this parasitic group which indicates evolution towards higher, complex organisms.
A baby's immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus's immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
