Birds have air sacs and lungs. When birds
breathe (in / out,) oxygen-rich air fills the
lungs and air sacs. When birds breathe
(in / out), the oxygen-poor air leaves the
lungs, and stored fresh air enters the lungs from
the air sacs. This means that birds always have a
supply of oxygen-(rich / poor) air.

How does the theory of natural explanation explain the medical phenomenon of antibiotic resistance?
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange.

A. The difference in elevation between land and water
B. The difference in cloud cover between land and water
C. The difference in density between land and water
D. The difference in specific heat capacity between land and water
Need a 100% correct answer please
Answer:
During the day, the sun heats up both the ocean surface and the land. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse.

use an analogy to explain the sequence of events in the replication of DNA
Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.

what is ecosystem ?
An ecosystem can be defined as a community of living organisms concurrence with non-living components, interacting with each other in an environment.
The structure of an ecosystem composed of both biotic and abiotic components which include the distribution of energy in our environment, climatic conditions prevailing in that specific environment.
The structure of an ecosystem can be divided into two components such as Biotic Components and Abiotic Components
both biotic and abiotic components are interrelated with each other in an ecosystem,. it is an open system where the flow of energy and components occur throughout the boundaries.
The functions of the ecosystem include regulates the essential ecological processes, responsible for the cycling of nutrients between biotic and abiotic components, maintains a balance among the various trophic levels in the ecosystem.

what are 3 parts of the blastocyst .
Answer:
outer trophectoderm layer (TE. trophoblast), an inner cell mass (ICM, embryo blast) and a blastocoel (fluid filled cavity)
The blastocyst is distinguished by the blastocoel, trophoblast cells, and inner cell mass.
What is blastocyst?A blastocyst is composed of an inner group of cells surrounded by an outer shell. The embryo will be formed by the inner group of cells.
Stage 3 begins when a cavity appears in the morula and ends when the embryo makes contact with the endometrial lining of the uterus and the zona pellucida is shed. Free blastocysts are stage 3 embryos.
Day 3 embryos are called "cleavage stage" embryos. The reason for this certification is that the embryo's cells are dividing (or cleaving), but the embryo is not growing in size.
The blastocoel, trophoblast cells, and inner cell mass distinguish the blastocyst.
Thus, these are the 3 parts of the blastocyst.

Explanation:
How does meiosis create four daughter cells from one parent cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell

What is RhoGAM? How does it work?
Answer:
RhoGAM is a medicine that stops your blood from making antibodies that attack Rh-positive blood cells. RhoGAM is a sterilized solution made from human blood that contains a very small amount of Rh-positive proteins. These proteins keep your immune system from making permanent antibodies to Rh-positive blood.
Answer:
Rhogam is human antibody to the Rh antigen. If any fetal blood cells escape into the maternal circulation, Rhogam binds to the Rh antigen and makes it “invisible” to the mother’s immune system. One dose at 28 weeks, and another at the time of delivery is enough to prevent the mother becoming sensitized.

If two roan cattle were crossed, what percent of the offspring would you expect to have a roan coat? Fill in the blank text field 1
Answer:
50%
Explanation:
I just did the question
If two roan cattle were crossed, then 50% percent of the offspring are expected to have a roan coat color.
A heterozygous individual is an organism that carries out two different alleles for the same gene locus.In this case, the 'roan' coat color is observed in heterozygous individuals (genotype R1R2).In consequence, the cross between two heterozygous individuals will produce a progeny in a 1:2:1 proportion.In conclusion, if two roan cattle were crossed, then 50% percent of the offspring are expected to have a roan coat color.
