Can an animal have no digestive system
Answer:no
Explanation:
Answer:
In other words, the platypus has no stomach. The stomach, defined as an acid-producing part of the gut, first evolved around 450 million years ago, and it's unique to back-boned animals (vertebrates).

in a school 58% of the total number of students are boys in the number of girls is 814 how many number of students are in the class
Answer:
See below.
Explanation:
Given that 58% of the students are boys, 42% must be girls.
42% = 0.42.
x = unknown number of students
0.42x = 814
x = 1938 (about equal to)
How is editing the genetic code different from artificial selection?
A It enables humans to influence the inheritance of DNA
B It enables humans to directly change DNA
C It can only be used on animal DNA
D It is not yet possible to edit the genetic code
Answer:
Option B
Explanation:
Artificial selection is influencing of inheritance of any trait . in this limited options are given to allow a species to mate and produce offspring
In genetic code editing directly genes are edited.
Hence, option B is correct

hope this helps you...In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM
Answer:
The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.
SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.

Explanation:
atmosphere is a present around the surface of the earth but it is not present around the surface of the Moon why
Answer:
tmosphere is a present around the surface of the earth but it is not present around the surface of the Moon because
This reduces the amount of gravity on the moon. Strong gravity is needed to hold an atmosphere into place. With weak gravity, gases that are emitted from the surface quickly are lost to outer space. Another reason is because the moon does not currently experience plate tectonics and geologic upwelling. Plate tectonics allows for a recycling of crust and convergence and divergence of plates occurs and this leads to volcanoes and gases escaping at the boundaries. The moon is said to be geologically dead.

Water Hyacinth is an invasive species that humans have introduced to many parts of the world. It is a plant that fouts on water and
forms groups. It can grow very fast. Over time, water hyscinth can cover the surfaces of ponde, lakes, and rivers,
What will happen to a pond where weter hyacinth plants grow and spread?
The water flow in the pond will increase, which can cause new plant species to grow
B. The amount of water in the pond will increas, which can cause new plant species to grow
C. The sunlight reaching underwater plant species will decreases, which can cause the plants to do
D. The temperature of the water will decrease, which can cause other plant species to die
Roset
Next Question
Answer:
C
Explanation:
This is the probably the most logical and correct answer. As the water hyacinth cover the surface of the water, the aquatic plants in the water will not have enough light for photosynthesis.

For the following question, match the key event of meiosis with the stages listed below. I. Prophase I V. Prophase II II. Metaphase I VI. Metaphase II III. Anaphase I VII. Anaphase II IV. Telophase I VIII. Telophase II Centromeres of sister chromatids disjoin and chromatids separate.
Answer:
VII. Anaphase II
Explanation:
During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach Anaphase II, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole
Which species are the most vulnerable to fungal infections?
a. Animals
b. Reptiles
c. Humans
d. Plants
Answer:
It depends, those who have weak immunity get the infections fast.
Explanation:
The species that are the most vulnerable to fungal infections are plants but is variable depending on the type of infection.
What is a fungal infection?Fungal infection is any type of disease caused by species from the Fungi kingdom (e.g., Basidiomycota species).
Plants are really susceptible to these type of infections (i.e., fungi infections).In conclusion, the species that are the most vulnerable to fungal infections are plants but is variable depending on the type of infection.

Explanation:
Hemochromatosis is an inherited disease caused by recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of all three children having a normal phenotype
Answer:
27⁄64
Explanation:
A recessive disease is expressed only when an individual carries two copies of the recessive allele (i.e., individuals must be recessive homo-zygous to suffer from the disease). In this case, both parents are carriers for hemochromatosis, i.e., both are heterozygotes carrying the defective allele, thereby the probability of having a child with a normal 'dominant' phenotype is 3/4, i.e., 3/4 individuals are expected to have an A_ genotype (1/2 AA + 1/4 Aa = 3/4), and 1/4 individuals are expected to have an aa genotype (where 'A' is the dominant allele and 'a' is the recessive allele associated with hemochromatosis). In consequence, the probability of having three children with the normal phenotype is 3/4 x 3/4 x 3/4 = 27/64.

what impact are these practices expected to have on soil pH and why?
Inherent factors that affect soil pH include climate, mineral content, and soil texture. Natural soil pH reflects the combined effects of the soil-forming factors (parent material, time, relief or topography, climate, and organisms). The pH of newly formed soils is determined by the minerals in the parent material.
