In a year, a population of lions had four births, two deaths from disease, one natural death, five emigrations, and five immigrations. In the same year, a population of zebras had five births, three deaths, four emigrations, and one immigration. Which best explains the data?
Zebras and lions are both experiencing a negative population growth.
Zebras and lions are both experiencing a positive population growth.
The zebras have a higher population growth than the lions have.
The zebras have a lower population growth than the lions have.
Answer:
The zebras have a lower population growth than the lions have.
Explanation:
Population growth can be defined as the increase in the number of individuals in a particular population. Population growth is negatively affected by the mortality rate and emigration rate, while it is positively affected by the birth rate and migration. In this case, the net population growth (NPG) of each population is equal to:
NPG lion population = 4 births + 5 immigrations -3 deaths (2 deaths from diseases and one natural death) -5 emigrations = 1
NPG zebra population = 5 births + 1 immigration -3 deaths - 4 emigrations = -1
Answer:
The zebras have a lower population growth than the lions have.

which of the following would astronomers most likely measure in light-years distance between stars distance between the earth and the moon?
Answer:
Astronomical unit usually refers to that unit which represents the mean distance starting from the center of the earth to the center of the sun. The distance from the sun to all the planets and other astronomical bodies are represented in the astronomical unit. It is denoted by AU. This unit is mainly used by the Planetary scientists and the Astronomers, as it is helpful in understanding the relative distance between two objects in the solar system.
Explanation:
Answer:
distance between stars
Explanation:
The distance between the Earth and the stars is enormous. As a result, larger units like light-years are useful for expressing these distances. When a star is eight light-years away from the Earth, the light from that star takes eight years to reach us. To put it another way, the light that we see today originated from that star eight years ago.
The astronomical unit usually refers to the unit that indicates the average distance between the earth's center and the sun's center. The astronomical unit represents the distance between the sun and all of the planets and other celestial bodies. AU is the abbreviation for it. Planetary scientists and astronomers mostly utilize this unit because it aids in determining the relative distance between two objects in the solar system.

What is affected by the electrical signal sent by the fourth structure of the reflex arc?(This will be the fifth structure in the arc.)
Answer:
The effector organ is affected by the fourth structure of the reflex arc.
Explanation:
When talking about the reflex arc, we refer to the sequence of events that occur for the body to react to an external stimulus.
In general terms, the peripheric nervous system receives information from a stimulus coming from the external environment. This information is sent to the central nervous system, where it is processed. From the CNS, another signal is sent as a response to the stimulus. This mechanism is known as the reflex arc.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
There are three types of neurons involved in the mechanism:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
Ascending branchThe stimulus reaches the body and is received by the specialized sensory receptors. Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy. Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.
Descending branchOnce the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response. Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.
Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.
Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.

Explain why biodiversity is essential to the health of an ecosystem Think about the complex interactions in an ecosystem and how different types of organisms respond to stable or unstable conditions Include evidence of factors that affect biodiversity and scientific reasoning to support your explanation
Answer:
Biodiversity is very essential to the health of an ecosystem.
Explanation:
Biodiversity is essential to the health of an ecosystem because biodiversity provides functioning ecosystems that provides oxygen, clean air, clean water, pollination of plants, pest control, wastewater treatment and many ecosystem services. The change of temperature of the environment greatly affect the organisms because the organisms needs specific environment for growth and development. Habitat change, climate change, invasive species, overexploitation, and pollution are the factors that affect biodiversity. These factors causes increase or decrease in the biodiversity of the ecosystem.

Answer:
A
Explanation:
The two genes are B and b are located in the same spot, therefore they are alleles or alternative forms of the same gene.
The diagram shown represents a pair of homologous autosomes. The letters B and b represents genes for a certain trait. These letters also represent allele pair that is containing the genes for the same expression.
What is allele ?
It is defined as the set of genes that are controlling the phenotype or genotype expressions of an individual.
Homologous autosomes have all the genes arranged in the same order but a difference in the arrangement of the letters in the genes are present.
While all autosomes present is homologous chromosomes not all homologous chromosomes are autosomes. Autosomes are 22 pairs of chromosomes in human cells. They are divided as homologous chromosomes as they have the same size and contain the same genes locations on each chromosome of the pair.
Autosomes chromosomes are same in length as well at the position from 60 to 200 mb in length. The set of genes that are opposite in nature but control the same expression where one is dominant and another one is recessive.

Mitosis vs. Meiosis answer chart
Answer:
why do cells divide is mitosis
mitosis is understood to involve five phases
how many daughter cells produced in mitosis two
how many daughter cells produced in meiosis four daughter cells
A condition in which every cell in the body has an extra set of chromosomes is not compatible with life. In some cases, a change in the number of chromosomes occurs only in certain cells. When an individual's cells differ in their chromosomal makeup, it is known as chromosomal mosaicism .
HOPE THIS helps
Explanation:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
[tex]\Large{\textbf{Mitosis:}}[/tex]
The cells undergo mitotic division to increase the number of cells to replace the worn out cells and for growth.In Mitosis, there are 4 stages, they are, Prophase, Metaphase, Anaphase and Telophase.In mitosis, cell divide once to form 2 daughter cells.In mitosis 2 daughter cells are produced.No, Chromosomal Number remains the same in mitosis i.e. 46.The final result of mitosis is two identical cells which are called daughter cells[tex]\Large{\textbf{Meiosis:}[/tex]
In meiosis, cells divide to produce gametes(i.e. sex cells) for the sexual reproduction.Meiosis occurs in 2 division i.e. Meiosis 1 and Meiosis 2(It is just Mitosis). The stages that are involved in these 2 division are 8.The stages of Meiosis 1 are,
(a) Prophase (which is sub-divided into 5 more stages which are Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis)
(b) Metaphase,
(c) Anaphase,
(d) Telophase.
The Stages of Meiosis 2 are, Prophase, Metaphase, Telophase and Anaphase which are same as mitosis.
3. In meiosis, Cell divides twice.
4. In meiosis, 4 daughter cells are produced.
5. Yes, the chromosomal number in mitosis is reduced to half than normal i.e. 23
6. In meiosis, the final result is 4 haploid cells. If meiosis occurs in male then these haploid cells will be called sperms, if it occurs in female then they are called Ova(egg).
_____________________________________Just to give you some insight knowledge of Meiosis Im adding some extra points
[tex]\Huge\textbf{Meiosis:}[/tex]
Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,
Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.
Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.
The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.
_____________________________________
[tex]\Large\text{Why is Meiosis Important?}[/tex]
Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.
It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:
During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity. During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'
